Avid shooter and mild gunsmith.
Bought the Hera Arms Comp for several reasons. Had a cool look and the length was perfect to add to my 7.5” barrel. It set up well with the length of my handguard and sticks out just past it. The company is designed to push gasses forward as well as the sound. As for the sound it’s still loud but does a great job of keeping gasses forward. In fact I don’t recall seeing any gas to affect the sight of the target. It’s a nice comp and seems to do what it’s drsigned to do. Again I bought it for looks and the fact that gas goes forward and not out the sides. This was purchased for my AR47 which has more recoil than I was expecting. Not sure if gas pressure going forward is making for more recoil to my shoulder.
