Multi-Purpose Rifle (&#8220;MPR&#8221;). This custom-built modern sporting rifle features an 18&#8243; nitrided alloy barrel with rifle-length gas system, Ruger&#8217;s 15&#8243; free-float handguard compatible with M-LOK? accessories, the Ruger? Elite 452? AR-Trigger and ergonomic Magpul? furniture. The perfect rifle for a variety of uses, the AR-556 MPR is capable and versatile.<\/p>\n<p>Ruger&#8217;s 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.<\/p>\n<p>The MPR&#8217;s cold-hammer forged 18&#8243; 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&#8243; journal for the low-profile gas block. The soft-shooting, rifle-length gas system paired with a Ruger? muzzle brake provides smoother operation and softens recoil to keep every shot on target.<\/p>\n<p>Ruger&#8217;s 15&#8243; free-float handguard is light, stiff and versatile, with Magpul M-LOK accessory attachment slots along the 3:00, 6:00 and 9:00 positions. Additional slots on the angled surfaces near the muzzle are perfect for mounting a light, laser or QD sling cup. Compared to a typical quad-rail forend, the 1.50&#8243; diameter handguard makes the MPR&#8217;s forend slim and controllable. M-LOK-compatible Picatinny rail sections can be easily added. The integral Picatinny rail at the 12:00 position is tightly controlled to the most current STANAG 4649 specification.<\/p>\n<p>The crisp 4.5 pound trigger pull of the Elite 452 two-stage trigger is a great addition to the MPR. The lower receiver is fitted with Magpul&#8217;s MOE? grip and Mil-Spec MOE SL? buttstock, making the rifle easy to handle, shoulder and shoot. The Mil-Spec compatible lower and upper receivers are CNC-machined from forgings and hard coat anodized. The MPR comes complete with dust cover, brass deflector and forward assist.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The new Ruger AR-556? Multi-Purpose Rifle (&#8220;MPR&#8221;).
