JL Billet 13" AR15 ULA Free-Float M-Lok Ultra-Lite Angled Handguard

The 3 picatinny rails in front and rear allow you to mount iron sights, optics and any other accessories without additional rail sections. The Magpul M-Lok system allows users to customize the handguard with rail sections and direct mount accessories. The handguard is constructed of 6061-T6 aircraft aluminum and finished with an optional Mil-Spec type III hard coat black anodizing

The ULA has a precision bore to fit the proprietary barrel nut which removes any unwanted play and ensures an exact fit!! Installation requires a 1-1/8" Crows Foot wrench (not included) for the barrel nut; standard AR-15 barrel nut wrenches will not work with this handguard system. The handguard is secured to the barrel nut by 2 10/32 allen screws, stainless steel key seat lock, and anti-slip helicoils.

  • Material: 6061 aluminum handguard, 7075 aluminum barrel nut

    I have this 13" handguard ( & others) & the machining, over all size, & the feel are perfect the cut out profile on the front compliments the muzzle break that is fitting and creative. the over all design is set apart from most other handuards If anyone is out to build a custom AR, this is a great addition to your build Thanks for being committed JL Billet
