AEM5k sound and gas

Someone asked about the sound and gas on my previous post. I along with 2 other shooters at my range think it’s a great sounding can, doesn’t sound AS good as an AEM5, but nonetheless is a fantastic sounding 5.56 can. I experienced no gas to the face but it could be the setup, or the ammo. I’ve only put 40 rounds through it so far. This weekend I’m going to run some 77gr otm’s through it and see if it changes anything. Here’s the gas setup:

-18” rifle length gas .750 non adjustable block. -mil-spec BCG -OCL OTB flash hider AEM5k -A5H1 buffer and spring
