Are you talking about the Tin BCG (Gold color) from DPMS? I did use that one. It was easier to clean by being gold not black. You have to use it with mil-spec chamber. What I mean is a custom barrel like Les Baer might give you problems. It will last longer dry compared to a regular BCG. But still need to lube it. It is better, BUT nothing like the XCR or AK. And that is with the DI system.
