Smith Enterprise HD 30mm Rings, MIL STD 1913, MED Details

NSN 1005-01-535-4423 Heavy Duty (HD) 30mm scope rings are some of the most combat-tested rings available on the market today. Unlike many competitors who use inferior sintered (i.e. powdered) metal manufacturing techniques, SEI’s HD rings are machined from solid 4140 CM steel for long life and utterly precise installation. The low configuration is designed to accommodate exit objectives up to and including 44mm, when used in conjunction with the SEI M14 Wire EDM NSN Mounts, P/N’s 2006 or 2008. The medium height version, developed specifically for and supplied to the US Army 25th ID, will accommodate rifle scopes up to and including 50mm exit objectives, to include those fitted with the KAC M14 RAS system and employing the SEI M14 NSN scope mounts. SPECS: 4140 chrome moly steel, heat-treated, black phosphate. Height: 0.500" (as measured from top rail to inside radius of lower ring) Item Nr.: 440-7018
