the lri is over double in price for a couple of oz if you are really buying it for the weight savings. Kmw seems like a very solid product and not overpriced like so much in the gun industrie. (Not knocking lri at all those guys do amazing work)
Not an ASR brake but i am also having major poi shift and accuracy issues with my brake. The rifle is an AR10 6.5cm. Best group i could ever get was .89moa. And that is after 500 rounds average was 1moa + Factory or handloads. Took the brake off and had a poi shift of 4.5 inches high at 120yds...
