One-piece aluminum Picatinny rail mount replaces the handguard – no gunsmithing! – to give your rifle a mounting platform for an intermediate eye relief scope, red dot, holographic or reflex sight. Low profile enables co-witnessing of the factory sights with red dot sights. Recoil lug, plus dual clamps attach quickly to any standard weight barrel without modifications. Mount remains in place during field stripping. Mfg: Ultimak SPECS: Aluminum, hardcoat anodized, matte black. Mounting hardware and instructions included. M14/M1A -129/16" (31.9cm) long. 12.4 oz.
