Introducing the M4 Patrolman's™ rifle series from Bushmaster® Firearms - the go-to hard-use duty rifle for both duty and sport shooting. Handcrafted in America and Proven® to perfection, this rifle series is built to withstand the toughest conditions while providing reliable performance.

What sets the M4 Patrolman's™ rifle series apart is the partnership with Franklin Armory® and their Binary Firing System® (BFSIII®) trigger. The three-position trigger allows for safe, semi-automatic, and binary firing modes. In binary mode, one round is fired on the trigger pull and another round is fired upon release, with the second round being cancellable via the safety selector. In semi-automatic mode, only one round is fired per pull, and in safe mode the gun will not fire.

The M4 Patrolman's™ rifle series comes with impressive specifications, including a 16" barrel made from 4150 CMV and finished with salt bath nitride. The barrel has a twist rate of 1:7 and a thread pitch of ½” x 28. The rifle also features a carbine-length gas system, a forged XM15-E2S™ lower receiver, and a forged A4 flat top upper receiver.

Other features of this rifle series include a salt bath nitride bolt carrier group, MPI tested bolt, M4 heat shield, M4 carbine stock, A2 pistol grip, BFSIII® AR-C1 trigger, BFSIII® ambi-safety selector, A2 flash hider, detachable carry handle, and a 30RD aluminum BFI® magazine.

Weighing in at 6.7 lbs without the magazine and measuring between 33-35.5 inches overall, the M4 Patrolman's™ rifle series also includes an F-marked A2 front sight. Please note that the BFSIII® trigger is not available for civilian sales in CA, DC, IA, NJ, NY, HI, DE, RI, FL, MD, CT, or WA.
