There are many bolt carrier group variants available in the AR15 aftermarket and many finishes to match. I am building a lightweight recce frankengun and want a BCG that is lighter than the standard 11.58~oz. I am considering the Cryptic Coatings Titanium BCG (7.78oz) in their mystic black coating. However I don't know if that is the right answer. They make many claims about their products such as smoother recoil and faster cycle rate. I don't know if any of it is true. I don't want to buy snake oil. Can someone tell me if I am wrong for wanting a lighter weight BCG? Does a titanium BCG make sense? Does their coating actually make that much of a difference?
