S 4 Launcher

I have here one of the few S4's that actually shoots.
it has been modified with 2 J&J barrels cut to fit. the bolts have been modified. I also removed the factory trigger guard and tank clamp, so I could run a 20 oz on it.
I use a drop oring and an on/off tank when I use this because the factory asa likes to eat orings.
It will shoot with regular co2 or siphon but it doesn't like compressed air.

I'm looking for $250 shipped. sold

Can you take pics of the internals laid out? I'm really curious why yours works and none of ours don't. I'm guessing it has something to with ours being first and 2nd gen and yours is the 3rd or fourth gen.

Alright I took her apart and took some nakid pics.





Now someone needs to post their nude pics. lol

From years of playing with VM's we learned that any form of drag on the upper bolt causes the gun not to recock, so what we do is shave the orings on the upper bolt if they fit to tight in the gun. I have done the same here on these "upper bolts".
The bolt is also drilled out and the face cupped, although that will have nothing to do with recock, just fps.
The valve uses a Vm valve stem(I can't remember if that was factory or if I did that) the valve has a large triangle cut through the center, which feeds the air for recock, thats where I would think to look.

Okay, that whole drive train has been uber tweaked the correct way with porting, lightening the hammer and creating antikink knobs for the bolts, which is what needs done for to solve the recocking problems. The valve itself needs looks to be brass which means it was made from scratch by the previous owner (most likely). The original valves were made from aluminum.

What is the velocity output of this S-4?
