View Full Version : Bolt Carrier Group

So I'm looking to build another AR15, it never crossed my mind that there are other options in bolt carrier groups but don't know the differences. I know I want something silver looking aside from the normal steel/black. What I saw was an aluminum & chrome. Any info would be greatly appreciated!

Chromed BCGs are for lubricity factor. Theory is Less Friction = Less Heat If you like the Silver-look, you'll love the Gold TiN coating :cool2:
