Features

The MK2 9mm Ambi Lower Receiver from Griffin Armament is a premium AR-9 platform engineered to serve as a durable and reliable foundation for pistol caliber carbine builds. Precision machined from high-grade 7075-T6 aluminum, this 9mm lower receiver is built to exact tolerances for consistent fitment with mil-spec components. A Type III hardcoat anodized finish enhances resistance to wear, scratches, and chemical exposure, ensuring long-term durability in demanding environments. Fully ambidextrous controls, including the magazine release and bolt catch and release, provide enhanced usability for both right- and left-handed shooters.

Designed as a dedicated Colt-pattern 9mm lower, the MK2 features a native magazine well optimized for Colt SMG-style magazines, eliminating the need for magwell adapters while improving feeding reliability. The integrated feed ramp system is precision tuned to align cartridges with the chamber, supported by a securely mounted nitrided 17-4 steel feed ramp for consistent performance. A combined ejector and bolt catch extension simplifies operation and reduces the need for manual adjustment, while a nylon-tipped tension screw allows users to fine-tune upper-to-lower fit. Built for reliability, compatibility, and performance, this ambidextrous AR-9 lower receiver is an ideal choice for custom PCC builds and 9mm AR platform
