hey great gun... I like the fact that you used a BV to make it breach loading

you should consider upgrading it to a 1/2" QEV and building a fridge compressor to use higher pressures

That's quite good! Take a bow. :)

I would add another barrel support closer to the end of the chamber.

Are you loading ammo through the ball valve at the rear?


Edit: Ahh, Poland Spud you Fast Fingered Freddy you! :lol:

@Gippeto sorry :D

@sinper2006 you built a very nice gun... have fun using it for a while... but when you decide to upgrade it replace that sprinkler valve - it's the only part that stops you from using 30 bar

That is a very nice gun.. What did you use for the barrel? also what size.I know you can get brass pipe nipples in custom lenghts. There perfectly smooth on the inside, no seam. You should upgrade to a stronger valve so you can take it up to higher psi..other wise the galvnized pipe is just over kill.

well have fun with it for a while
threaded parts give you the possiblility to upgrade it whenever you want to so its up to you whether you change the valve or not

i only got bout 20 m to shoot
that's more than enough :wink:

Nice job. Neat and trim unit there, not much to complain about. I agree with jrrdw, a stock would round it out.
