That makes it sound under-gassed. It can't hurt to try a heavier buffer if you have one, but I'm kinda stumped so far.

IMO, when they don't run, ARs can be almost as frustrating as M14s having accuracy issues. All the bits are tuned to work when everything else is in spec, when something is off it can be hard to find.

If Stoner had included an adjustable gas regulator in the original design, most of the AR operating issues could be easily addressed.
