The bolt carrier group is the heart of your rifle so it’s worth spending a little here. This one is mil-spec dimensioned for 5.56 and .223 and it’s finished in nickel boron. That coating is slick enough that carbon wipes off with a rag instead of a scraper and it cuts friction inside the receiver too. Many shooters run these with very little lube. If you’ve ever spent an evening scrubbing a BCG you’ll appreciate the difference.
