Welcome to the forum Gray. I'll go along with Edge on this one. I've got some 16" 308's (Armalite mid-length), and I also run the heavybuffers.com buffers. I also run muzzle brakes on mine also (oh yeah....they definitely pump up the volume). Between those 2 easy mods, they really smooth out the recoil. If you need more after that, you can always swap out the gas block for an adjustable type. But you usually only need to do that if you're gonna be running suppressed. I'd start with the heavy buffer first. That's a quick swap and worth every penny. And also like edge said, I run them on all of mine. You'll be amazed with the difference that'll make. Ron
