(4 customer reviews)


366 in stock (can be backordered)


The BKF AR15 MOD-1 Rail M-LOK series provides an alternative aesthetically progressive design that is lightweight with our 7075-T6 Aluminum barrel nut and attach method. The innovative attachment of the rail and the barrel nut provides a solid lockup, a seamless, strong joint that requires no timed alignment to the barrel nut itself. All BKF MOD-1 rails (and receivers for that matter) are designed with pocketed cutouts to further minimize weight. In addition, BKF MOD-1 rails offer QD mounting at the rear 3,6 and 9 O’clock of the handguard.

    It’s a very nice rail. It fits snug and tight on the barrel nut with four Allen head set screws. I will purchase another for a future build. I wish could post a picture of the build. Fully recommended.
