Helpful Positive Review Man oh man by walter capehart, January 20, 2022
Changed my AR from heavy to light. Finish is amazing. Accuracy is unmatched. I thought it was a little risky but I could not be happier with my decision. No huge change to my gun was necessary. Went right in. Love it more than my truck.
