BKF AR15 13″ M-LOK Handguard

(18 customer reviews)


197 in stock


Machined from a 6061-T6 extrusion, BKF standard line of free float handguards will provide you with a lifetime of service. The 6061-T6 aluminum barrel nut does not need to be indexed for gas tube clearance. The anti-rotation tabs are designed to fit a standard forged upper receiver and will ensure that the rail will not shift if the mounting screws come loose. The patented ASAL mounting feature ensures that there is no forward movement of the handguard and keeps it from shifting due to tension on the mounting screws. Anti-rotation tabs may be a tight fit on forged uppers, and may require hand fitting on billet uppers.

  11. Jaime (verified owner)

    not the tightest fit around anti-rotatiob tabs but we’ll worth the value

    Excellent Quality. This is literally the same as the Expo Patrol Rail for almost Half the Price! Same OEM? BKings Rocks! They have the best price and fast shipping as always.

    -Great Value, Great Quality
    -Great Finish. Isn’t chalky like other budget rails
    -Mlok Slots and Rails aren’t sharp or poorly machined. Easy on the hands.
    -Doesn’t seem to have much flex and seems sturdy.

    My only complaints:
    -No Instructions are included, but it’s easy to install. No Timing needed.
    -Aluminum Barrel Nut, I prefer steel.
    -May not work with billet uppers unless you file away the anti rotation tabs.

    Installation Tips:
    Barrel Nut Torque:
    40 Ft Lbs with Aero Shell. It’s an aluminum barrel nut. Don’t over do it!

    Set Screws with Blue Thread Locker Torque:
    Screws that thread into aluminum: 25 Inch Lbs.
    Screw that threads into anti slip steel nut: 30 Inch Lbs

    Always remember, less torque is needed with wet or lubricated screws.
