Fail Zero LIGHTWEIGHT Nickel Boron EXO Bolt Carrier Group - BCG

This low mass BCG provides smoother operation and less recoil resulting in faster target reacquisition for quicker follow-up rounds. This is critical in competition shooting and actual tactical situations.

This FZ Lightweight BCG runs as great as it looks! Like all FailZero products it is easier to clean and maintain, and guaranteed for life.

The increased lubricity from the Nickel Boron treated parts allows you to take full advantage of its lightweight profile. The slick surface combined with the lightweight carrier, creates very little resistance and allows the rifle to cycle smoother and increases reliability.
