Additional Information

Product Description



  • Lower receiver is fitted with Magpul MOE grip and MOE SL collapsible buttstock on the Mil-Spec buffer tube
  • Handguard is free-floating for accuracy and the slim, 15" length provides enhanced ergonomics and support
  • Made from aerospace-grade 7075-T6 aluminum forging, the flattop upper receiver includes a forward assist, dust cover, and brass deflector, and is Type III hard coat anodized for maximum durability
  • Bolt is machined from 9310 alloy steel and is shot peened and pressure (proof) tested to ensure strength, structural integrity, and durability
  • The Ruger Elite 452 AR-Trigger is a two-stage trigger that offers a smooth, crisp, 4.5 pound trigger pull. It features a full-strength hammer spring for consistent primer ignition and a lightweight hammer that enables a 30% faster lock time over standard MSR triggers
  • Rifle-length gas system provides smoother operation and reduces felt recoil
  • Magpul M-LOK accessory attachment slots along the 3:00, 6:00, and 9:00 positions with additional slots on the angled faces near the muzzle.
  • Cold hammer-forged 4140 chrome-moly steel barrel with ultra-precise rifling provides exceptional accuracy, longevity and easy cleaning. The 1:8" twist rate stabilizes bullets from 35 to 77 grains, and the 5.56 NATO chamber allows the use of both 5.56 NATO and .223 Remington Ammunition. M4 feed ramps provide improved operational reliability, and the matte black nitrided finish provides corrosion resistance
  • Chrome-plated bolt carrier inside diameter and chrome-plated gas key inside diameter provide exceptional resistance to hot gases. The gas key is staked so that it will not loosen after extensive firing. A matte black oxide finish on the exterior of the bolt carrier provides corrosion resistance
  • Ruger muzzle brake is a radial port design that significantly reduces felt recoil and muzzle movement. The 1/2"-28 threaded barrel allows for standard muzzle accessories to be installed
  • Also includes: One, 30-round Magpul PMAG

Excitement to shoot
I just purchased this rifle on the Fri the 13th, so hope it hasn't jinxed me. This is my second AR-15 and really excited to shoot it. I have a ruger pistol and I love that so that is why I bought this rifle. If it is as reliable as my gun I will be ecstatic.

This is my first AR. I bought it for area defense on my ranch. My expectations on accuracy were low given what I heard about what the military determined was acceptable. After making sure I was close to sighted in at 25 yds, I moved out to 200 yds. I was stunned when I checked the first group at only 1/2 inch. Two follow up 4 shot groups produced a maximum of 3/4 inch. I am pleased beyond belief. Only complaint is the 360 degree muzzle brake kicks up dirt when shooting prone.
