totally ripped off idea for full auto with a minor tweak, adjustment screws to change the compression of the springs on the piston.
basically a large pop off valve.

i have no plans to make a magazine or anything as i cant get ball bearings, most just made it to see if i could

new paint job

my kind of coaxial pistol gun made from aluminium extrusion and a modified blow gun. the barrel has a hole drill down into the lower chamber and into a alloy block where the air travels in a Z path through the block and the piston seals up against it as in a standard coaxial. a hole underneath the e...

my coaxial pistol gun. uses a carbon fiber piston, welded stainless steel chamber with 1/4 inch stainless steel barrel and pistol air blower as the trigger.

this is my old co-axial with suppressors attached to all venting points including the pilot valve exhaust. the suppressor on the front works very well and the vent air from the pilot valve was actually noisier than the suppressor on the front so i put a suppressor on that too. it takes a loud bang d...

the first backwards barrel sealer you reckon, im all happy now lol. yeah that is a soda water refill CO2 bottle. its threaded on to it, just uses normal 20mm metric thread. all you gotta do it depressurize it and unscrew the valve in it. also that blowgun is highly modified lol, gets about 3-4 times...

this is the sniper version of my latest gun. the old version is here: http://www.spudfiles.com/forums/viewtopic.php?t=5366& a little bit of cutting and soldering and i came up with this. much easier to aim and shoot, i'll have to do some chrony testing and that but the old version was getting pretty...

im sure it can go faster but the bike pump doesn't wanna go any higher lol
i was pretty much pushing my full body weight on it and it wouldn't go down lol
i'll hook it up to the compressor one day and do afew more tests, with some lighter ammo too, see how high i can get it lol

did a small chrony test at 80psi with a small aluminium slug
the results are pretty promising but i had to stop shooting as this thing is really loud and i dont really want the cops called lol

more tests to come....

shot at a brick house with a small bolt that half the diameter of the barrel with no wadding and got some pretty big chips
that was at 70 psi

im not sure what the pressure rating on the pipe is but im not gonna be taking it past 125psi which should be fine.

Insomniac is right on both of them

yeah i'll get some damage pics up aswell as some chrony testing

this is my brand new all metal gun, ive been meaning to build one for awhile just been trying to secide on a design. i came up with this, a piston housed in 2 tees. the pressure chamber is from a CO2 system used to make sodawater so im told, i was also told that it was empty when i bought it but i d...

yeah i just drilled a hole the same size as the OD of the barrel into a end cap primed and glued it then waited for that to go off then put some strong epoxy around the joint

the suppressor looks pretty much the same except the holes on the outer shell are twice as big.

well iv'e done some test with holes in the outer shell and no holes. basically i've found that holes in the outer shell reduce the sound much more than a outer shell without holes in it. i put as many holes in the barrel as it could handle and enlarged the existing holes in the outershell then i tes...
