The 16.1″ barrel on the new SR-556C features an integrally machined flash suppressor, which minimizes the overall length of the barrel while maintaining compliance with ATF regulations for civilian and commercial sales. The SR-556C maintains the mid-length gas system and the heavy (.850″) barrel contour under the handguard of the original SR-556, however the barrel under the handguard is fluted for weight reduction and to promote barrel cooling.
“Many of our customers appreciate the limited muzzle rise when shooting the original SR-556, which allows them to re-acquire their sight picture more quickly between shots,” said Todd Wilkinson, Ruger’s Chief Engineer for Rifles. “However, some customers requested a shorter, lighter, faster handling gun that can more quickly acquire separate targets. This new SR-556C drops a full half pound off the front end of the gun, which changes its handling dynamics considerably, something our customers are really going to appreciate.”
The SR-556C offers the same great features that made the original SR-556 such a success: it includes the two-stage piston driven operating system with a four position adjustable gas regulator; chrome plated, cold hammer forged barrel; Troy Industries Folding Battlesights, Quad Rail, and rail covers; chrome plated bolt carrier group and operating system, six-position stock, Hogue® Monogrip® and three 30-round MAGPUL PMAG™ magazines.
