The Ruger AR-556 is a series of affordable semi automatic rifles offered in a variety of chamberings. Known for its rugged reliability, the Ruger AR-556 is built on the popular AR-15 platform, pairing familiar controls and ergonomics with the dependability of the Ruger name.
The Ruger AR-556 is a semi-automatic modern sporting rifle with a milled gas block, a telescoping M4-style buttstock and ergonomic pistol grip with extended trigger reach.
The flattop upper is forged from aerospace-grade aluminum, includes a forward assist, dust cover and brass deflector, and is hard coat anodized for durability, while the 16.10” medium contoured barrel is cold hammer-forged from chrome-moly steel for longevity and easy cleaning.
Heat-resistant, glass-filled nylon handguards aid in comfort and durability, and the single-stage trigger, with enlarged trigger guard for gloved shooting, assists with reliable fire control. Rugged, reliable, and affordable, the AR-556 is chambered in 5.56 NATO/223 Rem and makes a suitable rifle for target shooting, home defense, hunting, and varmint control.
Ruger's AR-556 MPR rifle has a rifle-length gas system which provides smoother operation and reduces felt recoil. The matte black oxide chrome-plated bolt carrier inside diameter and chrome-plated gas key inside diameter provides exceptional resistance to hot gases.
Its lower receiver is fitted with Magpul MOE grip and a Ruger Elite 452 two-stage AR-trigger which offers a smooth, crisp, 4.5 pound trigger pull. The flattop upper receiver is made from forged aerospace-grade 7075-T6 aluminum, and includes a forward assist, dust cover and brass deflector. Its handguard is free-floating for accuracy and features Magpul M-LOK attachment slots along the 3, 6 and 9 positions. The threaded, cold hammer-forged, 4140 chrome-moly steel barrel with ultra-precise rifling provides exceptional accuracy, longevity and easy cleaning.
The barrel also provides M4 feed ramps which improves operational reliability, while the matte black nitride finish provides corrosion resistance. The AR-556 MPR has a Magpul MOE SL collapsible buttstock on the Mil-Spec buffer tube.
