bolt with dual tail orings so it seals the firing chamber. therefore when you
pull the trigger the entire firing chamber is always dumped, therefore i'm
running my pressure near 140psi and still getting 280's fps.
here's a thread on it: my mechanical ion project (pics) - PbNation
if you don't read the whole thread i shot it all day on co2 and got about 900
shots from a 20oz with no problems (no breaks at all). just adjusted the
trigger last night and now it's walkable (vid on second page of thread).
further plans may include a 'cocker style LPR before the 3-way to lower the
pressure holding the bolt back. should get less kick, better efficiency, and
lighter trigger pull, but may slow down cycle time a bit. |
can be done with less than $30 in parts (fittings/hoses/3-way/QEV), and i
could swap a board back in, in a few minutes. if you don't care about easily
swapping back and already have a QEV it'd probably cost you $10 and and
hour of your time. (these prices are if you have a local clippard dealer,
airsoldier.com has the parts, but will cost a little more).
