Switched over from a 10.5" DI setup that ran flawlessly on my CQB to the 12" piston kit. It ran fine for approx. 100 rounds. Cleaned it then experiencing a failure for the bolt to lock back on the last round most of the time...but varies according to lubricationit seems. This only occurrs with suppressor mounted in both supp. and fire modes... Wtf
To fix this I have tried...
Standard buffer
H buffer
H2 buffers
3 different springs
Various loads of ammo
30rnd Pmags
20rnd Pmags
A tapco 30rnd mag
What I have noticed:
When the gun is clean is will almost never lock back on the last round. If I strip off the CLP and frog lube (run separately) the gun then has a 50/50 chance of behaving right and locking back on the last round.
Called LMT and they recommended a H3 buffer so I have one on the way now. You guys have any pointers?
