FAXON GEN 2 9MM PCC FULL-MASS BCG

The FAXON GEN 2 9MM PCC FULL-MASS BCG (SKU: FF9MMBCGCNITRIDE) is a purpose-built power plant for 9mm AR-style pistol caliber carbines. Engineered to solve the common headaches of blowback systems, the Generation 2 model upgrades the critical failure points of the original design while maintaining its legendary broad compatibility with various lower receivers.

Whether you are building a competition-ready PCC or a dedicated home-defense PDW, this BCG provides the mass and reliability needed for flawless cycling.

Generation 2: Modern Enhancements

The Gen 2 BCG isn’t just a reprint of the original; it features several major upgrades based on real-world feedback from competitive shooters:

• Upgraded Extractor: Moves from the older internal “1911-style” claw to a more robust AR-15 pivoted and sprung extractor. This significantly improves extraction reliability and service life.

• Shear-Proof Design: The carrier key is now separate from the charging surface. This ensures that even aggressive charging handle manipulation won’t shear the key—a common failure in lower-quality PCC bolts.

• Easier Maintenance: Uses a standard AR-15 firing pin cotter pin, making disassembly for cleaning in the field much faster and tool-free.

• Enhanced Firing Pin: Features a stronger, heat-treated firing pin to handle the high round counts typical of PCC training.

Key Features and Benefits

• Full-Mass Weight (14.9 oz): The added reciprocating mass helps manage the violent nature of blowback actions, reducing “bolt bounce” and improving overall reliability.

• Broad Lower Compatibility: Features dual geometry cuts to ensure it runs flawlessly with Glock-pattern, Colt-SMG, and even MP5-magazine lower receivers.

• Ramped Bottom: The ramped design allows you to use standard Mil-Spec triggers as well as many common aftermarket triggers without needing a specialized 9mm-only hammer.

• Removable Carrier Weight: The internal weight is user-removable, making this BCG compatible with JP Enterprises Silent Captured Spring systems and other high-end buffer tuners.

• Full-Auto Compatible: Features an M16 cut, making it compatible with binary triggers and registered full-auto lowers.

Technical Specifications

Compatibility Note

While this BCG is one of the most compatible on the market, Faxon specifically notes:

• Spike’s Tactical: This BCG is not compatible with Spike’s Tactical Colt-style 9mm lower receivers due to their specific ejector geometry.

• Buffer Warning: Because 9mm blowback systems are harder on internal parts, Faxon recommends using a heavy-style 9mm buffer (typically 5.5oz to 8oz) to ensure maximum safety and service life.

Why Choose Faxon?

Faxon Firearms is a “parts-first” company, meaning they prioritize the engineering of individual components rather than just assembling kits. Their Gen 2 PCC BCG is finished in Salt Bath Nitride, which provides a surface harder than chrome and a lower coefficient of friction than phosphate, ensuring your rifle stays slick and runs longer between cleanings.
