I've got a 10.5" PSA upper that is very gassy to the face while shooting suppressed, to the point it's uncomfortable at times with eyepro. It has a BCM CH which helps a little I think, but I'm looking to knock it down a little more.. H3 buffer, chopped stock PSA A2 sight gas block.

Not sure what buffer spring it has, it might be one that came with a 16" PSA rifle.. Would an upgraded Armaspec Stealth H3 buffer spring help decrease that gas?

Mine doesn’t change how my gun is gassed.  It just makes it less “sproingy”.  I’d buy a Bootleg adjustable carrier.

Get a Radian Raptor SD charging handle, or any other Gas buster, or get a better can.

My form1 can has very little gas to face on 10.5, compared to a Q thunder chicken.

Running a SiCo Omega, happy with it so far. So you think just divert the gas via CH, instead of try to slow it down?

I'm trying to avoid adjustable stuff, gas block or BCG, just out of fear something comes out of proper adjustment and fails.

Adjust the gas. There are many options.http://www.blackrivertactical.com/concrete5/customtune-gas-port/

Same upper.
