People who know shooting understand that the "felt recoil" of a weapon is only partially due to the free recoil energy that hits the shoulder. Much of the "felt recoil" is actually the shockwave of sound hitting your eardrums making the gun feel like it recoils much more than it actually does.

People at the range constantly complain about my Grendel .308 with 18" barrel with compensator.

I'm all for compensator however the design you're hawking isn't a very efficient one.

This is a much better design.
