Griffin Armament MK2 9MM AMBI Stripped Lower Receiver, BLK
|
The Griffin MK2 9mm Ambi Lower is the ideal foundation for your next PCC build. Precisely machined from high-grade 7075-T6 aluminum to exact tolerances, the MK2 9mm lower is a premium carbine platform offering proper fitment and utility with mil-spec lower components. To enhance durability, the MK2 9mm lower is hardcoat type 3 anodized for superior resistance to surface wear, scuffs, scratches, and discoloration from cleaning solvents and oils. Included with this lower are Griffin’s ambi magazine release and ambi bolt catch & release controls offering increased usability for right and left-handed shooters. This 9mm lower is a Colt pattern lower capable of receiving affordable 10, 20, or 32 round magazines that have the classic Colt SMG look. It has a 1/4-28 Nylon tipped tension screw equipped lower for a tight fit that can be adjusted to fit end user’s preferences. The feed ramp and magazine interface in this system was improved over Colt. Rather than use a magazine well adaptor assembled to a 5.56mm lower with roll pins to remove excess volume of 5.56mm lowers, the magazine well was attractively and natively sized for the Colt 9mm magazine. The proprietary feed ramp was tuned to deliver cartridges perfectly to the centerline of the chamber of the barrel, unlike the original, pre Colt design which may not have involved a capable CAD system. The ramp is affixed solidly by three allen screws which pull the 17-4 nitrided feed ramp down into the receiver very aggressively utilizing a whistle notch type interface adapted from the CNC cutting tool industry for rock solid interfacing of the feed ramp. The ejector was combined with the bolt catch extension in one component that is intended to work properly as they are put together, needing no “adjustment of the ejector” as with the Original Colt system.
