Is that not good ammo in your experience?

There was quite a bit of chatter in another thread about it being poor quality. The accuracy is awful, but the stuff we have shot did run ok. The bottom line is the ammo would be my first guess.

^ Can confirm. Happy with both my older gas block insert and my gas tube. Used to think adjustable gas blocks were "cool" but the shiny wore off pretty quickly with the frequent tinkering and cleaning. Set it and forget it is the way to go if it works for your application.

Thanks so much for the help brothers. I went ahead and dropped in a Daniel defense bolt I had in my doomsday bag and it changed the ejection from 12:45 to 245 to 3. It’s also much more forceful. I swapped the old bolt back in and it went right back to pissing it out at 1 o’clock. Thanks very much. ! This Gun has run great for a long time, so I’m not gonna hold it against it that a little couple of springs got tired!

Nice. Glad it was an easy fix.

Glad to see it squared away. No concern abt brass ejection direction. That old ejection path "pie chart" is garbage.

Well! It's back. Now it is clearly over gassed. I can feel the bolt being more violent. And now if I run my surefire socom it will lock back with rounds still in the mag. The issue goes away if I remove my suppressor. I just ordered an EZ tune with the dedicated suppressor option for carbine gas.

Does it feel like the bolt catch spring is weak? Also, does it do this with different mags?

Agreed.
Random lock backs point to an issue with the bolt catch assembly.
