Hello fellas, some time ago I bought a light weight BCG for my Xanthos build that is no longer manufactured. Dunno what's up with that but it has been perfect to me. With the world the way it is these days, I'm wanting to keep spare parts for my precious. I seem to remember this bolt being "enhanced", having a thicker tail design. I know there is no "normal" spec for a 308 AR, but could anyone give me the outside diameter of your bolt tail and list what make it is? If I have to purchase an entire BCG, so be it. Thank you.
