Perfect for Pistols, SBRs, and Rifles
I’ve bought many of these over the years and they all have worked great. No issues with threads, coatings, or anything for that matter. As the title says they work great no matter what time of build you’re doing. However these are mil-spec so pay attention to what stock or brace you buy to avoid slop unless you don’t care about that like myself. It has never caused me any issues in the past.
