My 11.5" AR SBR has been having issues when suppressed. The bolt never locks back on the last round no matter what kind of mags im using or ammo I shoot. The odd thing is it will always lock back unsuppressed, but never locks back suppressed. It will also kick brass in the 2 O'clock position when suppressed. So I'm guessing its overgassed? I changed out the buffer spring for a heavier one, but it didn't fix the issue. I am also running a Spikes T2 buffer. And suggestions? Should I give the heavier T3 buffer a try?
Thanks
