Description

This product is 100% Made in the USA! Our gas tubes, gas blocks and even roll pins are all proudly manufactured in the US. All Complete uppers are headspaced prior to shipping and test fired.

The BKF AR15 M4 MOD-1 Rail M-LOK series provides an alternative aesthetically progressive design that is lightweight with our 7075-T6 Steel 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 M4 MOD-1 rails (and receivers for that matter) are designed with pocketed cutouts to further minimize weight. In addition, BKF M4 MOD-1 rails offer QD mounting at the rear 3,6 and 9 O’clock of the handguard.

  1. downingce (verified owner) –

    I’ve been shooting with this BKF M4 MOD-0 11.5″ Carbine since 2/2021, i’ve not had a single issue while using BFK’s uppers, I wish more people knew about how amazing this company is.

  2. Alexander (verified owner) –

    Phenomenal. Best upper length. Solid. Reliable. No issue when disassembled. Swapped muzzle break for a 3 prong. Went together perfectly with components from many other manufacturers. Definitly recommend. New customers they won with this one.

  3. Todd (verified owner) –

    This is my second upper from BKF. Both uppers have had zero issues. The first upper I bought was so reliable I purchased a second. For the price, these platforms can’t be beat.
