6.5G bolt
#4
Port pressure and/or dwell time.

Port pressure on CLGS is high.

Dwell time on 18” MLGS is pretty high.

16” MLGS with .076” port runs very nicely with an efficient carrier and sealed gas block.

18” Intermediate Gas System is really good as well.

18” RLGS is smooth, usually needs a larger port since dwell time is low, unless it’s suppressed.

I’ve had excellent results with 16” AA and 16” Lilja barrels, MLGS .076” ports.

The Monster logo barrels are cut with the same ports I think.
