Leapers UTG PRO M-LOK Free Float Handguard Features The Leapers Leapers PRO Handguard uses an ergonomic octagonal profile with thoroughly machined lightening cuts trimming weight without sacrificing the rigidity a free float design depends on for accuracy. Integral anti rotation tabs accurately align the upper receiver and prevent the handguard from rotating or flexing under use keeping the mounting platform consistent shot to shot. A patented steel barrel nut eliminates the need to time the gas tube or its installation screws simplifying the build process for armorers and home builders alike. At 13.10 ounces and measuring 1.33 inches in diameter by 1.53 inches wide and 1.99 inches tall the handguard adds minimal bulk to a completed rifle. This handguard is compatible with standard mil spec forged AR-15 upper receivers in both left and right handed configurations though compatibility with billet upper receivers is not guaranteed. The barrel nut fits over barrel diameters up to 1.05 inches covering the vast majority of AR-15 barrel profiles on the market. Proudly designed and made in the USA the handguard reflects Leapers long standing commitment to durable American made accessories. With 24 M-LOK slots across three tracks and four additional angled slots up front shooters have ample room to configure lights bipods slings and other accessories to suit their build.
