This is an interesting twist on an MLOK handguard.  The top picatinny rail has been milled off into an MLOK strip to shave weight. Amazingly lightweight for the length.

  • Comes with two mountable picatinny rail sections, each 60mm long (5 slots)
  • Aluminum body with steel barrel nut
  • Dimensions: 41 × 52mm (W × H)
  • Inside circular profile has a diameter of 35mm

Weights

  • 10" - 330g
  • 12" - 370g
  • 15" - 420g
  • 17" - 480g
  • Weights do not include Picatinny segments. Those add 24g each

    Compatible with:

    • All AR-15/M16 upper variants that use a standard barrel nut 
    • Some MLOK accessories (see note below)
    • All weaver and picatinny accessories for the railed portions 

    Installation Difficulty: 

    Tools required: 1-1/4" wrench, barrel nut greaseupper vice block, and torque wrench strongly recommended. The barrel nut has flats on it like a square nut, approx 30.5mm across, so you'll need a wrench for that, and it has to be low-profile to fit within 11mm wide flats. We recommend our Crow's Foot wrench which we designed specifically for these rails.

    Installation Notes:Some fitting might be required due to variance between uppers. Also, it is recommended to tighten the barrel nut between 30-50 foot-pounds of torque. These are installed similar to the Noveske rails with a large wrench on the flats in the center of the barrel. In a bind a set of channel locks or large spanner wrench should work or you can use a purpose built crow foot wrench.
