full auto QEV + relieve valve bullpup. with CO2 *UPDATE*

Unread postAuthor: Cosmic Muffin » Thu Sep 29, 2011 8:03 am

so i finally got my parts all together. chamber will be larger when its finally done, and of course the trigger mech will be attached to the barrel. havent actually testeed it properly for full auto because i dont have a continuous source of air, was looking at compressors today but the ones that go to the pressures i want are all too expensive. and i really cant be bothered making a fridge compressor... may have to hunt on gumtree for a second hand one. blow forward bolt is still under construction.
anyway pics >>>
