Ruger AR-15 Style Rifle.
Cold Hammer Forged Barrel.
Introducing the Ruger AR-556 Semi-Auto AR-15 Style rifle. This Ruger firearm features a cold hammer-forged 16.1 inch medium contour barrel that provides ultra-precise rifling for exceptional accuracy, longevity and easy cleaning. A 1:8 twist rate stabilizes bullets from 35 to 77 grains and the 5.56 NATO chamber allows the use of both 5.56 NATO and .223 Rem. ammunition. An ergonomic pistol grip features an extended trigger reach for more precise trigger control and the enlarged trigger guard is designed to allow for gloved shooting.
M4 Feed Ramps.
A-2 Style F Height.
M4 feed ramps provide improved operational reliability and a matte black oxide finish reduces glare and provides corrosion resistance. A Ruger flash suppressor is provided and the ½”-28 threaded barrel allows for standard muzzle accessories to be installed. The front sight post is elevation adjustable, and a front sight tool is included. The A-2 Style F-Height allows co-witness with many optics. The rear sight can be folded out of the way to make room for optics but can be instantly redeployed if needed.
Mil Spec Buffer Tube.
The handguards are made from heat-resistant glass-filled nylon for shooting comfort and durability. A six-position telescoping M4-style buttstock and Mil-Spec buffer tube allow the rifle to be properly sized for different shooters, or varying levels of outerwear or defensive gear.
