Product Details

These Bolt Carrier Group components add a pop of color and function in AR15 and M4/M16 platforms.

First, the BCG is coated in NiB-X. This is a proprietary Nickel Boron coating that provides long life, high reliability and easy cleaning and maintenance. NiB-X coating provides the optimal combination of hardness, wear resistance, lubricity, and corrosion resistance. The BCG components are coated and polished to reduce fouling adherence. This is especially beneficial in short barrel setups and suppressed platforms. NiB-X is guaranteed for life against chipping, spalling or flaking and was wear-tested with over 30K rounds in Government protocol endurance testing.

The BCG is available without color - just the NiB-X coating. But if you want that splash of color, the colored BCG's have a top-coat of Cerakote (over time and use, the color may show wear on contact areas - the NiB-X coating below the color layer will never wear). 

Pick one of our included in-stock colors or get it in any available Cerakote color. Just browse the Cerakote site here and pick your color (+$25). Let us know the color name and number when you select your product options, and be sure to only select from the H-Series colors.
