Each version of Iron City’s G3 Bolt Carrier Group is better than the last, and they’re all so much better than Mil-spec that you’ll think that cleaning components with traditional coatings is a hardship. Choose the TiN Bolt carrier group, the Copperhead or the sick black beauty that is the BlackDiamond DLC bolt carrier group. They all feature self-lubricity that makes them superior to Mil-spec coatings. They reduce wear on components, resist fouling and clean up beautifully. While each one has different inherent qualities, you can rest assured that whichever you choose will make you one happy shooter. And yeah, you can just pick the TiN bolt carrier group just because your wife likes the pretty gold bolt carrier group, we won't tell.

Choose any one of Iron City Rifle Works’ G3 BCGs from Wing Tactical and you’ll give yourself an edge.
