MK1 Patrol 13.9" 223W Carbine (Pinned to 16")

 Note: This rifle must be pinned with a 2.75" flash hider to reach an overall barrel length of 16" per the ATF. If you would like to purchase this length rifle without a muzzle device or without the muzzle device pinned, it must be formed as an SBR. Please purchase the MK1 CQB 13.9" SBR or MK1 CQB 13.9" Pistol.

The Griffin MK1 rifle series represents a full featured, quality, value packed carbine worthy of use as your primary carbine out of the box. Front to back Griffin rifles leave no stone unturned.

The MK1 Patrol 13.9" pinned 223 Wylde carbine is a true front line fighting rifle. The tuned mid length gas system and suppressor optimized buffer system ensure a soft yet reliable gas system suppressed or unsuppressed. The 416R SS barrel provides exceptional accuracy and durability. We ran one of these barrels to 47,000 rounds 100% suppressed while test firing suppressors with zero baffle strikes and the rifling was still present. The barrel was retired due to extension lug wear, not due to barrel rifling wear. Other case studies such as multiple M24 SWS barrels holding 0.35 MOA to 20,000+ rounds in army testing, provides further evidence that 416R SS is an extremely durable barrel material. 

Options include select muzzle device options and furniture color. This rifle due to its barrel length must have a pinned and welded muzzle device prior to leaving the factory, or be fulfilled as an NFA SBR with $200 tax required. The muzzle device you select above will be pinned and welded to the barrel.
