Thank you guys for the advice. I recently broke my charge handle. So while filling my cart on the brownells website I added a spikes tactical T2. I don't know about wear on the gun, but it definitely smoothed recoil/ helps keep on target for second shot. I also put on a levang linear compensator. In doing some google research on that one I actually found an old thread here on the fire and noone seemed to think it did any good. I ordered it anyway since it had 5 star reviews on brownells. I agree that there is no discernable noise difference while wearing hearing protection, but there is a difference shooting without. Don't take this wrong. It's still a 16" barrel and loud as hell but it does help. Anyways thanks again for sharing your knowledge and the advice.
