Hey everyone, I am new here, but not to 300 BLK.
Question: I am running a 7.5 inch SBR, with a non adjustable gas block, Armaspec captured H2 buffer, and Dead Air Sandman L. I am getting a lot of port pop to the point I should wear ear pro. Any suggestions? Thank you in advance for any help you can hook me up with!

Re: PORT POP
Choices are a longer barrel, smaller gas port, faster powder, enhanced BCG to delay opening.
Since you’re using 1680, that would be the first thing I would change.

300 Blackout, not just for sub-sonics.

Re: PORT POP
Depends on barrel length, gas system, bullet weight, and suppressor.
In general 1680 is my lass choice for subsonic loads because it's loud and dirty. But there are a few cases in makes sense.
