Shelved my muffs after being introduced to 3M Skull Screws by the range officer the other day, incredible sound dampening/deadening capabilities. Made the SG 3 stalls down sound like a .22, and the AR on rapid fire in the stall beside me was pleasant/wonderful. No more bulky muffs, made rifle work a joy, the HG was non existent and the 3 hour range session was way less fatiguing. A little pricier than your regular "roll and stuff" style plugs but definitely worth the extra scratch, got home and ordered more immediately.
