Precision-machined aluminum riser mount adds approximately .600' to height of flattop so primary optics can be positioned higher for a more comfortable, heads-up shooting stance and faster target acquisition. Eliminates the need for extra-high rings in most installations. Top of mount is angled 20 MOA to compensate for added height and minimize effect on point-of-impact. Provides a full 7' of usable mounting length, 1½' more than receiver rail; underside of extension is relieved to provide clearance over handguard. Precision CNC machined from lightweight, 6061 T6 aluminum billet, with MIL-STD 1913 Picatinny slot-and-rail spacing that allows fast and simple adjustment of eye relief, plus greater flexibility in choice of optics. Clamps securely to receiver rail with three heavy duty steel cross-bolts to prevent movement under recoil, and matches receiver profile for a smooth, seamless look. Accepts Picatinny and Weaver-style scope rings. SPECS: 6061 T6 aluminum, hardcoat anodized, matte black. 8.875” (22.5cm) long, 1.125” (2.9cm) wide at base. Adds .600” (1.5cm) to height of flattop at rear, .570” (1.4cm) at front. 7.7 oz. (219g) weight.
