Ruger Ar-556 Mpr 5.56x45mm Nato 18 inch 10+1 Hardcoat Anodized Finish

The Ruger AR-556 MPR brings practical range-ready engineering to the AR-15 platform with an 18" cold hammer-forged 4140 chrome-moly nitride barrel, 1:8" twist and 5.56 NATO chamber that stabilizes 35—77 grain bullets and accepts .223 Rem., making the MPR series a go-to for precision varmint work, training drills, and duty-style applications. The flat-top 7075-T6 upper with Type III hard coat anodizing, forward assist and brass deflector pairs with a free-float 15" handguard with Magpul M-LOK slots at 3, 6 and 9 o—clock to allow low-profile accessory mounting while preserving accuracy; the rifle-length gas system and mil-spec 9310 shot-peened bolt smooths cycling and reduces felt recoil, which is further tamed by Ruger's radial-port muzzle brake and threaded 1/2"-28 barrel for standard muzzle devices. The Ruger Elite 452 two-stage trigger delivers a crisp 4.5 lb pull and fast lock time, and the lower comes fitted with Magpul MOE grip and MOE SL collapsible stock for ergonomic control and adjustable length of pull. Built with chrome-plated BCG gas key staking and a nitride-finished bore for corrosion resistance and easy cleaning, this semi-auto rifle weighs about 6.8 lb with overall length from 35" to 38.25", making it a reliable choice for target shooting, training, and field use where durability and consistent accuracy matter.
