SPVMBR

Well here is a little gun I threw together lately.
The name stands for Silenced Piston Valved Marble Rifle(SPVMBR)
Here is the gun
I gave it a satin black paint job(that turned out rather nicely) and I made a silencer for it.
The silencer is not very affective at all, but it does quiet it down somewhat. I realize that an effective silencer needs to have lots of volume, but if I made a larger one it would have ruined the looks.
And I wouldnt go as far as calling this thing a sniper as it doesnt have a scope and you cant shoulder fire it(stupid ball valve).
So here are the specs
Chamber:24in of 1in sch40 pvc piping
Barrel: About 40in of 1/2in sdr21 pvc pipe(I havent measured so Im just guessing)
Piston valve:1in tee with 1/2in porting
Pilot:1/2in ball valve
Piston1in wooden dowel with neophrene sealing face bolted on
Silencer1in sdr21 body
Well so about the power.
The power is very good for a gun so small(as shown in the videos)
And it is loud for its size(as said before, the silencer is not that effective)
I know it is very similar to my ISM but I wanted something better looking, and a little more manageable.
So pic and vid time
First some vids, then some pics.
