Ruger has announced its new AR-556 Multi-Purpose Rifle (MPR), a custom-built AR-15 design that features an 18-inch nitrided alloy barrel with rifle-length gas system, Ruger's 15-inch free-float handguard compatible with M-LOK accessories, the Ruger Elite 452 AR-trigger and Magpul furniture.

"We are very excited to add this model to our modern sporting rifle lineup," said Ruger President and CEO Chris Killoy. "Our talented team of engineers worked carefully to develop the ideal custom package for the AR-556 platform that does it all, right out of the box. From plinking to competition shooting, the MPR is the perfect rifle for just about anything."

The MPR's cold-hammer forged 18-inch alloy barrel with 5R rifling is salt bath nitrided for corrosion resistance and durability. The barrel is contoured to minimize weight without sacrificing rigidity, leaving a 0.75" journal for the low-profile gas block. The rifle-length gas system is paired with a Ruger muzzle brake to provide smooth operation and reduce recoil.

Ruger's 15-inch free-float handguard is designed to be light, stiff and versatile. Magpul M-LOK accessory attachment slots sit at the 3:00, 6:00 and 9:00 positions. The 4.5-pound trigger pull of the Elite 452 two-stage trigger is a new addition.

The MPR will ship with an MSRP of $899.
