Waiting to hear back from Aero on the carbine buffer, in the meantime the rifle buffer setup from Midway came in so I set it up with that and a MI muzzle brake.
Bolt can no longer touch the lower, does not go far past the hold open, id say 1/8 max
Shot L2 ball this time to test, heres the breakdown
-1 round loaded, fired and locked back
-10 rounds loaded, fired, cycled 10 locked back, much less recoil than first outing
-Let a buddy shoot 5, 2 shots then click, didnt load. repeat, then shoots last and locks back
-He shoots 5 again, first 3 are single shots again, ejects but no new shell picked up. Last 2 cycle fine and bolt locks back
-I shoot 5, first 2 single shot then 3 run fine and lock back
This is repeated roughly for 10 more shots then I pack it up.
The parts are all DPMS per Midways site, I would have gone with an armalite spring but was trying to save on shipping. I will get one if it would really make a difference, im back to being at a bit of a loss on this thing
Any more thought or suggestions welcome
ETA the bolt has always been fairly difficult to pull back and doesnt slide into battery if ridden forward, it will close with a light tap of the FA though, It just doesnt seam to lock and unlock smoothly or easily, dont know if this is just because all parts and springs are bigger or what
