Ruger has announced the AR-556 semi-automatic, M4-style, direct impingement Modern Sporting Rifle, and is proud to report that all major components are being machined at the company's Mayodan, N.C., facility.

"The AR-556 is the first firearm designed and built in our Mayodan, North Carolina, facility, and we couldn’t be more thrilled with the finished product,” said Ruger President and Chief Operating Officer Chris Killoy. "Through extensive design review and product testing, our Mayodan team has delivered a solid rifle that our customers will be proud to own—and and we are proud to call a Ruger."

The AR-556 is constructed from forged 7075-T6 aluminum upper and lower receivers, and a cold hammer-forged chrome-moly steel barrel with M4 feed ramp cuts. Chambered in 5.56 NATO, the AR-556’s carbine-length, flat-top, M4 design is fully configured with a Ruger Rapid Deploy folding rear sight, milled F-height gas block with post front sight, forward assist, dust cover, and brass deflector.  Other features include a telescoping six-position stock, improved trigger-reach grip, enlarged trigger guard and one 30-round Magpul PMag.  Standardized M4/AR components are utilized throughout, so the AR-556 can be customized easily.

The Ruger AR-556 was extensively tested during its development, with over a quarter million rounds expended during the final validation, endurance, and Ruger “jury” testing. MSRP is $749.
