FailZero 9mm AR9 Bolt Carrier Group - Nitride

The FailZero 9mm AR9 Bolt Carrier Group is fully assembled and fits most 9mm AR-platform rifles and pistols, compatible with Colt and GLOCK-style magazines. Constructed from 8620 steel, it features a staked gas key that acts as a carrier guide to keep the BCG oriented correctly in this blowback design.

Features:

• Compatible with GLOCK and Colt-style magazines
• Chambered in 9mm
• 8620 heat-treated (mil-spec equivalent) carrier
• Salt bath nitride finish
• Staked carrier guide (gas key)
• 5.56 extractor, heavy duty
• Chrome-plated firing pin

Every component besides the firing pin is salt bath nitride finished for increased hardness and lubricity, making it wear resistant and easy to clean. The heavy-duty 5.56 extractor helps keep a 9mm AR-15 running reliably.

FailZero is the pioneer of Nickel Boron coating technology for firearm components, delivering permanent dry lubricity and extreme wear and corrosion resistance across their bolt carrier group line.
