I know this is kindof a Marq knockoff, but I just was fooling around.



The black things you see behind the "Cup bolt" are black rubber wing-like projections. The one on the top is to keep balls from falling behind the cup. The ones on the side (both sides) are for stability when the bolt is in it's foreward position (rides in a groove in the side of the body) and to keep air from traveling up the feedneck. As you can see, it kinda mimicks the Alien bolt designs, only allowing air to hit the bottom part of the ball.

The blue is orings. 3 in the design.
The bolt tip is made of rubber to help make it more gentile on paint.

Any suggestions?

your desing doesnt seal the chamber when the bolt is foreward, this means it will pour out air while the bolt is cycling, giving low efficency, and horrid cosistancy.

and as for as "low blow" bolts go they dont really accent the ball effect as much as say a flatline (not trying to compare) your design probably uses a circular and free rotating boltsystem, you would need a way to keep the bolt sysytem from rotating and to keep the "low blow" portion at the bottom of the breach.

hmm a cocking knob perhaps? or you could create groves in the back of the gun for an indention of the bolt to go that way it will stay in the right position. creating a actuating valve of some sort would help the gun to seal off the firing chamber.

Quest type bolt... take a look at the porting on it. This is pretty much my Clutch Marker design, but without the self arresting bolt and quick disconnect bolt.
