Manufactured by FailZero, this BCG features an advanced Nickel Boron (NiB) coating that provides exceptional lubricity, corrosion resistance, and ease of maintenance.

Why Choose the FailZero Nickel Boron 6.5 Grendel BCG?
The 6.5 Grendel cartridge is popular for its excellent ballistic performance in the AR-15 platform, but it requires a properly built and reliable bolt carrier group to function consistently. The FailZero FZ-6.5 GRENDEL BCG is engineered specifically for this caliber, featuring a Nickel Boron coating that significantly reduces friction between moving parts. This self-lubricating property means less maintenance, smoother cycling, and improved reliability, especially during high-round-count sessions. The Nickel Boron finish also resists carbon buildup, making cleaning much easier compared to traditional phosphate-coated BCGs. For shooters who demand maximum performance and minimal downtime, the FailZero Nickel Boron 6.5 Grendel BCG is an outstanding upgrade.
