The continuous top rail allows 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 MLA has a precision bore to fit the proprietary barrel nut which removes any unwanted play and ensures an exact fit!! Installation requires a 1-5/16″ crows foot wrench (not included) for the barrel nut; standard AR-10 barrel nut wrenches will not work with this handguard system. These rails are some of the lightest you will find anywhere! The 15″ weighs in at only 10.9 oz. including the barrel nut. Available in Low, High, and Armalite profiles.
