Single expansion chamber uses exiting barrel gases to neutralize recoil and dampen muzzle rise. You get a softer shooting rifle and quicker follow-up shots. Lightweight, smaller-diameter muzzle brakes match the lines of the thinner barrel contours used on lightweight, mountain-style rifles. Made from heat-treated chrome-moly or stainless steel. Bore exit hole is .242" and must be opened up to .020" over bullet diameter during installation.
