Watertown, WI – December 23rd 2024 –
The Griffin MK2 9mm PCC series are fully ambidextrous 9mm AR-15s, and are the first full-ambi 9mm AR-15 on the market with a forged 7075-T6 receiver set. They are Colt magazine pattern lowers capable of receiving Colt or Metal Form 10, 20, & 32 round magazines. The lowers are built with a 1/4×28 nylon-tipped tension screw for a tight upper-lower fit that can be adjusted to fit end user preferences. These guns feature the same full-ambi control suite our customers have come to love from our MK2 series of 5.56mm AR-15s.
The feed ramp and magazine interface in this system was improved over Colt. Rather than use a magwell adapter assembled to a 5.56 lower, the magazine well on the MK2 9mm was natively sized to accept Colt SMG magazines. The proprietary feed ramp was tuned to deliver cartridges perfectly to the centerline of the chamber of the barrel, unlike the original Colt design and is affixed via a “whistlenotch” geometry borrowed from CNC drill holders, by three allen screws which pull the 17-4 nitrided feed ramp down into the receiver aggressively for more reliable feeding. 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.
The buffer is brass for increased weight and is sized to limit the travel of the BCG so that casings cannot become lodged in the fire control pocket. Coupled with a proprietary action spring, the operation is very smooth and nearly recoil-less. These 9mm guns come equipped with Griffin’s New Adjustable 2-Stage Triggers, which are configured at the factory for functional use right out of the box, but can be adjusted for overtravel and second stage/disconnector engagement by the end user for a more refined feel if they prefer. This Griffin Armament match trigger is a Milazzo Kreiger style 2-stage trigger, combining a mil-spec 62RC 8620 trigger material and heat treatment regime with a 53RC 440C tool stainless disconnector, and 440C 53RC nickel teflon coated tool steel lightened speed hammer.
Griffin MK2 9mm PCC’s come in three barrel lengths at this time; 4.5” with 7.5” SR handguard, 9.5” with 13.5” SR handguard, and 16” with 13.5” SR handguard. 4.5” and 9.5” models are fitted with a Griffin 3-Lug barrel adapter, and are best paired with the Griffin Sportsman Ultra Light HD™ .36or Bushwhacker® .36 suppressor fitted with a 3-Lug booster interface. The 16” model comes fitted with a Griffin Taper Mount Flash Hider Muzzle Device, and can accept Griffin Taper Mount suppressors, or any HUB-mount suppressor equipped with a Griffin Taper Mount (Plan-A™) HUB interface.
“Making the Griffin 9mm guns was a fun project for us. We were aware of the multiple issues that 9mm PCCs typically struggled with, such as feeding reliability issues, and we wanted to solve some of these issues in a MK2 series full ambidextrous platform. The proprietary feed ramp and ejector design is the most notable of these improvements over the original Colt SMGs, and allows for much more reliable feeding of 9mm cartridges including hollowpoint ammunition. We chose Colt magazines for aesthetic reasons and for reasons of better suitability to the AR-15 platform, to keep the classic SMG look, and to maintain the AR-15 manual of arms. Combining these factors with our buffer system produced a really soft-shooting PCC that we think our users will enjoy.”
