I put together a Noveske 10.5" .223/5.56 SBR and been running it unsuppressed with an H2 buffer and flatware spring (tubb precision I think). Ran flawlessly for a year, than I had an itching for suppressors. Running now with a Sig 762TI, occasionally the bolt won't lock back on an empty mag. If I take off the suppresser (no flash hider), bolt will lock back consistently on empty mag.
I've read dozens of threads, but can't definitatively wrap my head around which way I should go with the buffer weight. Current thinking is dropping down to H would probably work, although there are moments when I think an H3 is correct. Can someone save me some time and verify which direction I need to be going?
Thanks in advance for your help,
Noah
