AR suppressor problem

[DiggeR12]

Im trying to figure out why an AR in 7.62x39 operates fine when unsuppressed but jams every shot or every second shot when firing suppressed?

Shooting from a 16” barrel and a SilencerCo Omega300

is the rifle with suppressor on not getting enough gas to operate correctly or maybe getting to much gas and failing to operate correctly? Any ideas?

Thanks ahead of time.

Probably Too much and is severely over gassed

^ I'd bet that! You're running the bolt too fast for it most likely.

Could try lower power ammo. Easiest would be to throw a heavier buffer in there and see if it changes.

Adjustable gas block or Adjustable carrier can help/fix too!

Way over gassed. Too much gas can do weird things.
Saw it in a 6.5cm build.

Likely way too much gas.

Can I take too much gas for 500? Jk.

Too much gas. Slow down the bolt
