    My favorite comp

    Published by John on 11th Nov 2019

    I put this comp on everything 223 people are always impressed with how low the recoil is and the price is awesome. Also I like that it is stainless steel because I prefer SS barrels. If you're on the fence just buy it you won't be disappointed. I've purchased 3 so far and will get a new one for every new ar I get.
