Hey Guys. Could someone tell me more about these half circle vortex blocks. Is the rof higher than a full circle? I've seen a pic of one in a flamethrower but it did not have a air line hooked directly to it. Does that mean it is more like a cloud? Any input would help. thanks

Thanks rcman, I bought a gearbox on ebay. It is a motor driven gearbox activating a spring loaded piston. The bbs are fed through a tube opening in front, like a sub machine gun(m3, mp-40). It looks like it was in a gun that was magazine fed. It is operated by an electrical switch. Sorry, I can't se...

I just built a browning 1919 copy. I mounted an aeg gearbox inside. I have a 30 cal. ammo can mounted on the side that I would like to use as to hold the bbs. Can anyone advise me as to a feed mechanizim? Thanks
