Radical Defense MK1 Mod 1 Patrol Features The Radical Defense MK1 Mod 1 Patrol runs a 14.5 barrel fitted with an RD Suppressor KFM Taper Lock flash hider that is pinned and welded to bring the total barrel length to 16 keeping the rifle configuration legal without NFA paperwork. The carbine s patented threaded straight gas tube and gas block work together to eliminate gas leakage at the block a common failure point on standard AR-platform rifles while helping tame recoil for faster follow-up shots. A Battle Arms Development RACK ambidextrous charging handle lets shooters manipulate the action from either side of the receiver a real advantage for both left and right-handed shooters. An ambidextrous selector and enhanced trigger guard round out the fully ambidextrous controls Radical Defense built into the platform. The MK1 M-LOK handguard is thermal fit to a steel barrel nut with a Tombstone lock-up system resulting in an extremely rigid mounting platform for lights lasers and grips without any wobble under recoil. B5 Systems furniture including the Bravo stock and B5 grip gives the shooter a comfortable adjustable point of contact that has become a favorite among duty and competition shooters alike. A Nickel Teflon coated single-stage trigger breaks cleanly and resists corrosion far better than a standard mil-spec trigger. Topped with Griffin Armament M2 iron sights and fed by a 30-round magazine the MK1 Mod 1 Patrol arrives ready for patrol duty home defense or range use straight out of the box.
