FAILZERO NICKEL BORON EXO BCG
We're pleased to offer the FailZero EXO for sale, a bolt carrier group designed for the M16 but also preferred for M4 and AR15 builds. Requiring no lubrication for installation, the EXO NiB bolt carrier group fits perfectly into any upper receiver and provides smooth chambering with reduced friction between each round, thanks to its nickel boron coating. Although this full-mass bolt carrier group is heavier than your standard BCG, the added weight adds to the part's reliability and performance as it can withstand thousands of rounds before showing signs of wear.
