Edit: my barrel is 6.5"
Okay, I have built many AR rifles but my current build is a little different than my norm.
I built a 300 blackout pistol with onl a 6.5" barrel. The gun works well with supers and it will eject the spent rounds on the subs but don't quite get back enough to pick up the next round so it won't chamber the next round.
I put a compensator on it and I thought once suppressed it would have enough back pressure to function properly but even with the suppressor it still is having this problem.
I originally had an adjustable gas block but that block would not let me screw on the flash hider quick disconnect for the suppressor so it is sporting a cheap non adjustable gas block at the moment. That said, even with the adjustable one it was having those problems.
Any idea on how I can make this gun cycle better? lower weight buffer, different buffer spring? Something else?
Here are a few pics of the gun.
