Suppressor Gas in the face

[Crookhunter]

We run OSS Suppressors. They are legit and have minimal blow back, even for lefties...

I opened the gas block all the way until the screw fell out and it still wouldn't lock after the last shot.
I'm pretty sure it's not the magazines either since they're P-Mags that don't cause issues in other guns.

You may want to check that the gas block is aligned correctly to the port in the barrel. If the block is misaligned that will contribute to the gas in the face and LRHO of the bolt.

already checked, and Yes it was NOT aligned and I fixed it and checked to make sure it was in the right place. I may double check.

Superlative arms makes a piston kit. And SilencerCo just released a charging handle that is supposed to defeat all gas blowback. If you ran an adjustable gas block, you could shut the gas off and run it as a single shot.

Adjustable gas block and a 30 cal can will help with gas blow back. I’m a lefty btw.

Ok.

Locking back issue fixed. Adjusted the gas block and the heavier buffer did it.
The gas in the face issue is serious. At one point I gasped for air and caught myself shooting with my eyes closed.

I’m going to close the gas block as much as I can to where it’s still ejecting near 3:00 and locking back but reduce the extra gas. Also ordered an E-Brake hoping some/most of the gas exits at the muzzle and doesn’t come back…

Lastly a muzzle rise when I shoot fast… maybe the e-brake will help with that too.

Oh, I forgot to say, I have a Skeletonized BCG that I may use. Not sure what it will do!

Check this out.
The new military Sig M5 Spear will be issued to ALL troops with a suppressor and one of the features is. Sig has found a way to eliminate that gas port blow back with their can and adjustable gas block. Discussion about gas blowback starts at 11:37
Next gen AR design that addresses old issues.

Late to the party, but I don’t have this issue with Left handed side charging upper receivers.

I drilled a small hole.098 in the side of my charging handle (YouTube) and black rtv on it also where it mates with the upper, run an adjustable gas block also.

It’s also a .556 issue. Tons of pressure in that round. I have found that all my .556 guns blast me more with gas than my other calibers. I too suffer from the lefty syndrome.

Do you have a link for this?

What barrel are you using? Most ar15 barrels are severely over-gassed. Being a lefty, you are always going to get some gas, but a properly gassed barrel will help a lot.

Criterion 10.5" 1:8 Twist Wylde.

I need to play with the gas block and see if I can close it to reduce some of the gas and still lock back and eject properly. I also ordered an E-Brake hoping most of the gas exits at the muzzle.
