BAM B50/51
My first PCP was a BAM B50 in .177. I had to drive through half the country to get hold of it. My first shot with a PCP was at a road sign. People on the parking lot never knew what happened. Soon i traded the B50 stock for a B51 stock, it looked a bit better. I have had a few BAMs....
There`s not many pictures left of the first PCP. Here they are. Two with the B50 and one with the B51 stock. 2007
We all know the BAM B50/B51 is a copy of the Daystate Huntsman MK 2 even though there are lot`s of differencies. BAM uses metric, Daystate uses Imperial threads, trigger parts aren`t interchangeable and there is more. But nevertheless all hell broke loose on the Dutch airgunforum when the first BAM appeared. QSA, the Dutch Daystate importer got as mad as hell, word was that everyone that bought a BAM would have his ass sued off, every shopkeeper that would import BAM was going to be sued too!

Next step was telling everyone that the BAM was made of inferior material and a bursting airtube was a matter of time, dead and mutilation beyond compare for the owner of a BAM.
A tombstone with
"You had it coming, poor sod you are!
HARHARHAR!"
written on it was all that would last.....
Two years later, obviously -and against all odds- i survived my first BAM, i bought another one. A .22 B50. I got it out of the States, www.airgunexporter ya know? That was in 2009, after selling the .177, i bought another one, a .22.
I have proved to be a compulsive wank....no, a compulsive BAM-buyer. In 2011 i bought another one. A B50 in .177. I wanted to join the (H)FT world.Luckilly i didn`t get that far, dunno what stopped me, but it did.
I didn`t get any further than making a lighter hammer to get the BAM to the maximum of 12 foot pounds. On the pics an original hammer, the one i made on the lathe and a polished original.

I sold all of `em. Only thing i did with a BAM was repaire `m. And see Hanzerschreck turn a BAM into bigbore airguns.
Some picture of BAM parts.
There`s no such thing as constant quality in BAM PCP`s. Every barrel needs cleaning when the gun comes out of the box, most valves are going to break after a limited number of shots, some BAM`s look like they`ve been transported through an oil pipeline from China to the Netherlands, that`s how greasy and oily some of `m are.
In 2013 there was this bloke on the shooting range, told me he had bought two BAM`s. Two because the first one took to long to arrive by mail, so this bloke went to buy another one so he could shoot. I traded one of his BAM`s for a filling set and an aircontainer. When i asked where he got the BAM from i knew imediatly. It`s one i had before. It was the .22 i bought in 2011 and sold pretty quick.
The gun cane in the stock of a Logun Professional, it had an easy life. Hanzerschreck gave me a thumbhole stock, i painted the gun black and now my daughter is pretty happy with that BAM. It runs in the family `ey!?
Here`s that BAM, in the Logun stock, in a Daystate X2 stock, in a rat-like thumbhole stock and in the Oldskool Fokke Mol FT stock.
Ain`t life grand?
Now ten years after the first BAM in the Netherlands we can state that the BAM B50/51 has proven itselves. There`s no other airgun that i know that didn`t loose any of its popularity and power. It became a classic in its days. Not many airguns have done that.
The trigger is great, barrels are good, the finish of the gun varies strongly and about everyone hates the brass bolt. But everybody loves the gun.

Yet another BAM
and making a .25 of it......

In the summer of 2015 i was kinda forced to trade my last BAM for a lathe. Every summer i bought one, sold `m after the holidays again when i could use the lathe on my work again. This time i got an offer i couldn`t refuse. Trade a BAM for a lathe.
Later that summer i got a mail from a Belgian friend, Ric. A friend of him was fighting with a ragged old BAM. They planned to throw the gun away, would i want it? For parts or so. My heart jumped. Sure i will!


This particular gun was bought new in 2007 and got a Daystate stock somewhere along the way. I didn`t mind at all. One thing got clear to me. I like a BAM, it`s a great little gun, fun to shoot, technically very simple, a great platform to build things up on. After a few months i decided to make a .25 of it. Technically in great shape but with an overall appaerance of a cheap ass  gun that came straight from the waste area. Like it was supposed to be one day.
Some bloke from the Dutch airgunforum sold a .25 barrel. Hatsan. Arite. That`s mine.

After some work on the lathe the new barrel fitted in de BAM breech like it was made for it (it was actually!). Cut of some of the length of the barrel to get to transfer hole in the barrel in line with the transfer hole in the breech. Took some of the outer diameter off to be able to glue a tube over the barrel to make the barrel fit the breech. The tube was made of an old rusty .177 barrel from a Cometa V.
I drilled two holes in the top of the breech for two bolts to keep the barrel in to place. A simple job. Next thing to do was make the  hole in the breech a tiny bit bigger. It wasn`t possible to get a .25 pellet through that hole as it was. A reamer was long enough to enlarge the hole a few tenths of a millimeter. Simple job too, as long as you have the tools.
The outer diameter of the barrel was too big for the (Daystate) barrelband on the BAM. To the lathe again.
Time to build the gun and see if it`s able to shoot. I didn`t do anything to the valve and it`s housing until now. Just see what the gun is doing in this set up. Some last pics....
Tonight i have taken the BAM .25 to the gunrange. I shot it at some 145 bar, the JSB King did 260 m/s. Not too bad for an almost standard BAM doncha agree? Ik dropped the presuure to 130 bar and the pellet did 250 m/s. Now it`s time to mount another valve spring, another upgrade is to enlarge the transfer port in the valvehousing.
This BAM contains parts of Daystate, Hatsan, FokkeMol and BAM.
I gave the Koejak! another probe. Had it lying around somewhere. It shuts the barrel off a bit better. I`m gonna have to make a new probe someday, a little larger in diameter. The Koejak had parts of Daystate, Hatsan, Fokke Mol and BAM. With this probe the Koejak! adds Air Arms to the list. The pic above is taken at the Noarderloft Gunrange. What you see is the Koejak resting on a Caldwell rest, a 10 liter industrial 300 bar container, an Aqua Environment regulator and a high pressure hose from Best Fittings. Pellets are from JSB. The Koejak! was ment to be a short distance plink gun but i took it to the 100 meter range and it showed me its potential.

BSA Techstar
a Techstra is born.

The second PCP i bought was a BSA Techstar. It had two owners before me, and the first one did something special with it. Here are pictures of the Techstar is i recieved it. In Real Tree camo and with a BOS 10X50 scope. An awesome gun, giving 40 fpe. And what`s better, i still got it!
After three years the itch got unbearable. How does this gun look onder the Camo sheet? I wanted to know for a long time, so i went to the shed and peeled the Camo sheet off. Underneath the Camo skin was a brand new looking Techstar. People called me an idiot for getting rid of the Camo colours. They were right, i never admitted it tho`.
The Camo jacketed Techstar was a well known airgun, kind of a VIP. Everybody knew that gun, and everybody liked it. In its original appearance the Tech is a very simple gun. An airgun in a Lada Niva stock. It should`a been made in Russia. Hell yeah!
Little did i know then.
This is the second transformation of this gun.
Like always, when you have something for a long time you`re getting bored with it. I started to dislike the MMC knob so the Tech stayed on the shelve more and more. One day a friend of mine had a Falcon stock for sale. Hmm...does it fit the Tech? It did, i bought and my friend`s old man started milling like a mad man. I put a GinB triggerguard on the stock and at the end of the day i went home with the best looking Techstar in the world.
And the Techstra (Frysian for Techstar) was born.
Transformation nummero three.
But still there was the MMC, and because the Falcon stock is longer than the Techstar stock it became even more irritating to use the MMC. Around that time there was this Dutch genius called Huub that gave his BSA a side cocking bolt. Like on a Shinsung 201. I got inspired and made the Techstra SC. Thanks to the Dutch genius for his inspiration. So i went to work started the lathe, drilling machine and mill and on the end of the day...... BSA Techstra SC
Transformation number four.
When some guy sold the breech, valve housing and magazine of a Hornet i didn`t take too long. I bought it To get to tranformation number 5  i`m gonna make this a multishot Techstra.  Take a look!


A Techstar is one of the best airguns ever made, it doesn`t break, it shoot hard, it`s acurate and it`s simple.
I made the Techstar a side cocker in 2011. I kept the parts all the time. This week was the week that i needed those parts. I made a Techstar from the Techstra again.
I took the Techstar out to Noarderloft, the shooting range where i usually shoot.

BSA Scorpion T10

This BSA appears to be an airgun from East Germany, grey-ish black, a stock made from some synthetic material, an airgun for the minimalistic gunman. The only highlight in its colourscheme was the chrome bolt. The gun in black, i know what would happen if Johnny Cash had been an airgunner....
My Scorp was one of the first generation with the bolt jumping up with every shot. The gun was poorly adjusted when i got it. A lousy 15 shots from one filling. I got the gun so far that it did 2 mags on a fill, never got more out of it. After 5 months the bolt came out of the breech. The latch pin broke clean off. One of the little diseases of the Scorpion. I brought mine to the importer, QSA (now Airgun.nl). A few weeks later i got the gun back. Everything but the stock was new. Mk1 became MK2.
I found some pictures on a forgetten SD card. A Scorpion single shot. Looking at the pictures the gun must`ve had some trouble with filling. Or did the retaining cap come loose? Must have been something like that.
But the pics are great, it`s a very nice airgun. Well kept and well oiled and such.

BSA Lonestar 1

I haven`t told ya, but there have been two occasions that my Techstra moved elsewhere. I once sold it and i once gave it away to a friend. He helped me out on some building project. During that time, somewhere last year i woke up and i felt i wanted a BSA PCP. I knew a former shooter had one, i called him and i bought his Lonestar.
When i got it in my hands i was pleasantly surprised. As pleasantly surprised as when i heard the intro of Joe Szabniak New York Junk`s "Passion of the 10th street blues NYC `77" played live in Vienna. Pleasantly because the Lonestar was one of the very first made in 2008. The last Techstars got a new stock and were sold as Lonestars while they actually are nothing else but Techstars. It`s pretty simple to see. The Lonestar has the higher breech and the maintube of the Lonestar is made out of two parts and on the Lonestar`s breech it says 'Lonestar', on the Techstar breech it says 'BSA Guns'. There are more differencies but these are less visible.
The BSA PCP`s are sturdy but there`s one thing that is able to spoil the fun. The brass valve seating bush tends to come loose from the backside of the valvehousing in wich it is screwed in. When the valve seating bush get`s loose it blocks the hammer and the gun will become very inconsistent. You will wonder what`s wrong, but before you know it the brass parts is completely deformed and unusuable.

BSA Lonestar 2

This Lonestar is a real one. Let`s take a look the differencies between the Techstar and the Lonestar. I have revealed some in the part above. Let`s concentrate on the internal changes. The maintube of a Techstar is made of three parts, the Lonestar has two parts. The valve housing and filling port is made of brass while these parts on the Techstar are made of steel. The Lonestar`s poweradjuster differs from the one in the Tech wich has an Allen screw for adjusting the power of the gun.
And here`s the Lonestar in parts.

BSA Airsporter MK1

This BSA Airsporter is a very special gun for me. I inherited it from my brother in law. He bought it when he was young, and this airgun had a special status in the family since the day it got there. The Airsporter is a classic. The production number of this gun tells it`s a MK1, that means it is made between 1948 and 1954. That means this gun is at least ten years older than me. In 2007 i changed the mainspring, since that day it didn`t shoot 100 pellets. Until yesterday, i did many shots with it, together with a Gamo Hunter 440 wich is 10 years old. The Airsporter is a miracle compared with the Hunter 440.
The Airsporter is a well made airgun, it`s not strange that a gun build like this one still shoots after at least 60 years. I don not give any tender love or any care to this gun. Every now and than i take an aerosol and spray the gun from top till toe with oil. WD40, Teflon spray, whatever. This gun deserves to be treated that way. There`s many ladys of the same age that look - or try to look- like they`re in their early twenties.
This old lady doesn`t mind to have the appearance of a 60 year old.

Below an impression of the sights of this gun. Battered for 60 years but still working pleasantly. Front and backsight are installed by a dovetail connection. A gentle tap with a lightweight hammer takes care of adjusting the windage.
Below some different pics of the action of the Airsporter.

BSA Lightning

This BSA i had for just a short while. I bought it at a shoot but after a week i got bored with it even though this Lightning is a real BSA. The trigger is well known and is a reminder of the triggers on a BSA PCP. The build in silencer made it a silent gun. I remember the Lightning being very pelletpicky. I had a .22 barrel with it, but i found it to be an underpowered airgun. Underpowered airguns bore me. So i sold it.
Not just a silencer on the barrel but there is some kinda silencer under the scoperail. Two rubber strips make it a Dampa Mount feature, it seems to save scopes.
Some more pictures of the Lightning.

BSA Lightning XL Tactical GRT .177

Lotsa people saw it coming. Fokke buys every gun twice. Ashamed i admit that i sometimes do. I have to! Some guns i have to have for a second time because the first time i didn`t have the patience to get a proper meaning about the gun. Or maybe i just forgot? I really don`t know and frankly i don`t care. This gun i bought from a friend of mine, Ferdinand. He`s got lots of guns, he`s worse than me in any way. I planned to buy this Lightning some year ago, the gun didn`t function so Fer didn`t want to sell, he brought it back in working order.
The gun looks pretty in this picture but in fact it`s a scruffy piece of used metal. I don`t give a hoot about the looks of a gun, i care about how it shoots. This one`s got a gasram and i like that. I own a HW90 too and i am really fond of the feel of a gasram.. No twang, no rattling just a mere 'tsjok' and that`s it.
There are some differencies between these guns. Some are supplied with a Gamo trigger (wich seems to be horrible), some of `em are made in Spain and some of `em are made in Great Brittain.
This trigger doesn`t look like a Gamo trigger to me. I love Gamo because they`re the reason BSA airguns still exist but i don`t like Gamo airguns at all. And i don`t like Gamo triggers. This Lightning is supplied with an aftermarket Theoben gasram. It does some 12 Joule and that`s not too much. It`s kinda underpowered just like the first Lightning i have had.
The Lightning has a feature that makes it a famous airgun. The Volumetric silencer. There are no baffles inside the silencer so the gun is not really silent. The silencer makes the gun look good and that is the only contribution of the so called silencer.
The Lightning is the smaller of the three small springers i`ve got. The Weihrauch HW97K is a 'karabiner' with its 102 cm (40.1"), the Air Arms TX200HC is even smaller; 99,5 cm (39.1"), the Lightning is just 95 cm (37.4) tall. But it`s a great gun!
There are two kinds of Lightnings, the ones made in the UK and the ones made in Spain. Since BSA is an old UK firm i like the UK version better. I know that Gamo bought BSA in 1985 and i am kinda gratefull for that. If Gamo hadn`t bought BSA there would be no more BSA airgunfactory left. Demised like the English motorcycle factories, the English motorcar industry, there would nothing be left.
The push rod of the Spanish Lightning is horribly bad. Instead of making the push rod from old fashioned English steel the push rod was made of chewing gum. The UK version of the Lightning has massive push rods. Aftermarket parts are usually Spanish wich bend to uselessness in some 500 shots. I altered my push rod, made it from three pieces of chewing gum welded together, i riveted the parts together and it seems to work allright. I`ve done some 1500 shots up to now.
But there are details that make you smile. This tactical stock is for the right handed and for the right handed only. The thumb rest in the stock goes as far as the end cap of the action. The very pronounced cheek piece on the left, the roll over on the right side and the sharp edge on the front of the cheek piece.
Pics like the ones above are my favorite. They`re showing all the dirt and all the beauty. Rusty airguns give me a bad mood so i better keep `m oiled. The barrel is chamfered  in a way the pellet can be placed easily. The latch notch shows wear and there`s goo pouring out from under the barrel seal. Airgun porn. THere`s a wooden stock on its way. Can`t help wanting this gun in another stock. It`s too light to be a serious plinker, i need my guns to be a bit heavier. Best thing would be a wooden stock modelled as a tactical stock.
I got the feeling that`s gonna happen someday....
Some guy at the club came up with a Lightning with a wooden stock. I had the idea to give mine a wooden stock too. Much to my surprise he told me he had a stock lying around somewhere wich he was planning to sell. Arite man! Gimme gimme! The stock looks better and the gun shoots better. Think because it`s heavier. There`s one thing that has to be done. I want an adjustable cheekpiece so the stock is travelling to the wood sorcerer in a few weeks.
As soon as i got the wooden stock i knew i had to get it modified at Airblower. He is the Emperor of the Adjustable Cheeckpiece. The Lightning is the second gun Airblower has worked on. Take a look. It`s not that the stock of the Lightning wasn`t any good but i simply isn`t perfect. Now it is. Take a look.
I learned today that the hard to get Tactical stock of the MK1 doesn`t seem to fit the last version of the Lightning.

BSA Superten MKI

A true classic airgun is this BSA Superten MKI. It`s the first PCP built by BSA. It came to see the light in 1996. BSA didn`t mind taking a few risks entering the PCP market with this gun. It`s regulated, has one of the best triggers i`ve ever encountered. John Bowkett, the brain behind this airgun, has delivered something outstanding. There have been three versions of the Superten, technically they were about the same, the stocks made the differences.

It`s obvious this S10 doesn`t have the original buddy bottle aboard. The official MKI bottle has a round bottom. This gun is fitted with a quickfill! And i am very pleased about that.
The Hammer Block of this BSA broke clean off after two shooting sessions. Suddenly the gun lost is consistency and its power and after three more shots the gun didn`t even get cocked. I took the stock off of the gun and something fell out. The Hammer Block. A new one is hard to get, better make it yourself!
I had to take the gun apart, i usually get to that point but not because i gun is broken, i`m taking `m apart because i`m curious! Anyway, taking a gun apart is getting to know the gun. A few years ago someone asked me to repair his S10, he gave me a cardboard box full of loose parts. I didn`t succeed in getting the gun together again. At that time i didn`t have a clue what was wrong and i didn`t have a clue how the gun exactly worked. All them safetys on this gun must have made me confused. No i`ve taken apart a working gun (exept firing) i knew how to get it apart and how to get it in working order again.

From top down: The probe, the hammer, the hammer spring and the all new Hammer Block. I had a hard to get a new Hammer Bl;ock. Mark Knibbs didn`t have any in stock and didn`t expect ever to get`m in stock again. That`s fucked up. Finally i got me a Superten, i shot it maybe 100 times and it breaks down never to shoot again? My topic on the greatest airgunforum on this planet -Luchtbuks.net- attracted some viewers and i asked one of `m to help me out on this one. He did. Some weeks later the all new hand made Hammer Block got here.
Next thing i did was putting the Superten together again. I took the occasion to get rid of the nasty safetys BSA put in the gun. I do not trust any mechanical safety devices.

After getting the gun together again i took a few shots. The greatness of the gun is undisputed for as far as i `m concerned. It`s obvious this gun is almost 20 years old. It`s a solid gun, a high end gun, This one is as good as any and better than most. I took it to the shooting range the next day and shot like never before. I`m shooting on a 100 meter track, pellets are the JSB Exact Jumbo of 15.89 grain. Look at the groups i shot with this gun.
On the pic at the bottom the lower hole was the aiming point. These are all 5 shot groups.
If you ever get the change to get hold of a Superten, just buy it. This almost twenty year old airgun beats most modern PCP with two fingers up its nose...

BSA Goldstar .22, 10 shot springer

In 1992 BSA presented the 10 shot Goldstar as the worlds first commercial repeating airrifle. I knew this gun existed but over here it is as scarse as a unicorn. On the Dutch airgunboard a mere three Goldstars were mentioned. This is one of those.
Picture
Click here to edit.
I saw this particular gun being sold on the Dutch airgunboard, it went to Belgium. I just missed the opportunity. A year after the purchase i sent the owner a PM and asked if he was willing to sell te gun to me. He wouldn`t. Okay, that`s cool enuff. A few months later i got a PM. If i was interested in buying the Goldstar. Sure. Name your price. In no time the gun was in my hands. I never shot one, never even held one.
The underlever isn`t a small gun, it is 108 cm long (42,5") and it is a bit out of balance. it weighs some 3500 gram (close to 8 LBS), the 46 cm (18") barrel isn`t choked.

BSA R10 SE Black Edition .22

After the debacle with the AEA Challenger Pro i needed a gun that stopped me disliking shooting. The bloke i got the AEA from sold this BSA R10 so i traded in the AEA and a few days later the R10 was mine. The stock has a synthetic appearance but it`s a wooden stock painted with some rubber like spray. The feel is great. It`s kinda soft. The stock is ambidextrous. The balance of the gun is pretty good. 
And i have to say that i am kinda fond of BSA airguns.
The butpad is multi adjustable just as the two stage trigger is. There`s not much negative to say about the trigger ecxept that the first stage is kinda long but that`s oke with this great trigger. The position of the trigger is adjustable in length and the trigger shoe can be adjusted from left to right. Both stages are adjustable too.
The R10 is Regulated. In the MKI the BSA Regulator wasn`t all too good. I don`t really know if the MKII regulator is better but mine has a HuMa regulator anyway. In all my honesty i am convinced that HuMa regulators are the best. The shotstring is very consistent. The power of the gun is a bit low, i am using 14.3 grain JSB pellets to get some velocity. These JSB`s do an average of 276 ms 905 fps.
I have stored the BSA R10 for a while. It was leaking. I was even planning to sell the R10.  The gun is a bit boring because it is aim and hit and because the gun is underpowered i did not take it to the 100 meter range. When it started leaking i had enough of the gun. After some six months i took it out of storage to repar the leaking.
The R10 tends to leak at the filling port. It sure did. I changed the o rings and i had to seal every screw with Loctite as you can see on the pic below.
The R10 is airtight again and when i shot i couldn`t help but liking the gun. I decided to keep it. The R10 is a smooth operator. The trigger is okay and till 70 metres you can hit anything you want. With the HuMa regulator the gun is pretty consistent too.

This gun isn`t goin` anywhere. It`s here to stay.

Benjamin Marauder .25

The Benjamin Marauder is a relative newcomer in the world of PCP`s. It`s not a fancy gun, it does what it`s  supposed to do. In the US shooters are making the most beautifull creations of a M`rod but over here in Europe it`s not a cheap gun and a modded M`rod is hard to find. Lucky for me this one started leaking like crazy so i offered to fix it. Not that i am the good Samaritan of broken airguns, i`m just a nosey bloke who wants to know what`s inside a gun. With the air gargling throug the barrel it was clear what was wrong. A leaking valve.

Time to take the gun apart, curious what we`re getting to see.
The trigger guard is made of an ABS like synthetic. The designers of Benjamin had an off day. It`s not the most beautifull and delicate trigger guard i`ve ever seen. Anyway, removing  the Allen screw get`s the action from the stock. The fitting is very tight.
Next thing is removing the breech from the tube. There`s not much to it to be honest. Loosen the four tiny Allen bolts. A small insert in the breech makes it a left or a right handed gun.
The two bolts at the rear of the breech and the screw at the rear of the triggerhouse keep the end cap in its place.
The endcap comes uot of the tube and so does the hammer spring, the hammer and the hammer spring adjustment screw. The adjustment screw was screwed in too far and lying loose in the tube not giving the spring the tension that was ment to get.
There are some things i do not understand. Why put the safety this close to the trigger? It`s crazy. Air Arms puts its safety IN the trigger, that`s even more inconceivable, but Benjamin`s solution is crazee too. For as far as i`m concerned there`s only one safety; the guy that holds the gun. Would you depend on some mechanical device?
The hammer`s travel is adjustable too (like every hammer`s travel should be). The hammer`s travel is one of the main adjustments of an airgun. To get any balance the tension of the hammer spring and the travel of the hammer should at least be adjustable. The hammer isn`t the prettiest example of fine machinery i`ve ever seen, i`m saying that in all modesty.  One tenth of a millimeter would`ve made it a smooth looking hammer instead of this scratchy piece o` work.
The front cap had to come off too. The front cap is fitted with the only solution to filling the gun. A Foster male. Why can`t all airgunmanufacturers use a male Foster? All the hassling with tenthousand and one filling adapters makes ya crazy. There`s a decent filter in the front cap to avoid getting dirt in the tube. Nothing wrong with that!
In most PCP`s the lid of the valvehousing presses the o ring into an airtight seal. This valvehouse doesn`t use that solution. Just a plain o ring is enough to get it airtight.
The problem with M`rod was a leaking valve. The valveseating is very thin and left it`s mark in the valve. A thin valveseating is an easy way to get an airtight seal but it is vulnerable.
This is an easy thing to repair. Put the valve in the lathe, sharpen a toolbit and cut the imprint of the valve seating away. Replace the valve and start shooting. That`s what i thought. The gun was leaking as hard as before. Dafuk? The valve was broken, you can see it in the red circle.
There`s no .25 valve available so the owner of this gun chose to buy a new valvehousing. There`s a difference between the two valves i bought. One is a MK1 and the other one is a MK2. Drilling some holes in de valvehousing, 3 mm is deep enough to give the bolts the space they need.
The bolts that keep the trigger unit in its place need some space. The valvehousing on the picture right above has some room for the small bolts. The valvehousing on the left doesn`t. The pics below show the remedy i used to solve the problem.
This gun hid a regulator. It`s an aftermarket HUMA regulator. The HUMA reg is made by Marc and Huub, two dutchmen with some creative dna. These regs are good.
Putting the gun back together is a piece of cake, some edges on the inside of the tube are kinda sharp.....
