Exceptional AR Muzzle Brake!
Exceptional Muzzle Brake! The fit and finish were outstanding. No cheap matt blue finish. This is a high-quality AR Brake...you get what you pay for. The added washers (multiple thicknesses) will easily allow the user to "time" the brake. Just wrap a layer or two of masking tape around a round shank screwdriver and place through the side ports to tighten. The ports visible on top in the photo are the only ones on the brake, i.e., there are not small ports on the top left, indicating that this brake is designed to help keep the rifle down and to the left, similar to the AK-47 slant brake. The short of it is this...this brake works awesome! Almost no recoil movement and the noise is not objectionable with basic ear muffs. No need for double protection like some other designs. It's also smaller, in my opinion than it looks in the pictures. It's only slightly larger than an A2 flash hider and looks great on any AR. Worth every penny!
