BKF M4 MOD-1 8″ M-LOK Handguard

(8 customer reviews)


160 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.

    Super light, excellent machining! Will work perfect with my 9 inch 300 blackout barrel and suppressor.

  7. Brian C. (verified owner)

    I really like the look and feel of the hand guard. The only downside is the QD holes are a little too big to retain a QD attachment for the sling. Had to buy an M-Lok QD mount so I could securely attach my sling. Other than that I love it.

    One of the locking screws was stripped, but everything else all good.
