I put them on all of my intermediate to long range riffles - Dead Air Armament Key-Mo Muzzle Device

I use them on anything I plan on shooting over 500 yards. They cut recoil in half, reduce muzzle flip, and help with follow up shots. Like any muzzle break they are obnoxiously loud but I always shoot suppressed so they act as a sacrificial baffle for me. I recommend them for SPR’s, large-frame AR’s, even bolt guns.
