Product Description

What's in the Box

  • Ruger AR-556 MPR 350 Legend Rifle
  • (1) 5-Round Magazine
  • Cable Lock
  • Owner's Manual

The AR-556 MPR has proven to be an excellent hunting platform, and the .350 Legend chambering expands that role. The nitrided 16.38" barrel is capped with a 1/2"-28 radial port muzzle brake. The rifle's appeal is enhanced by the combination of a Ruger® Elite 452® AR-Trigger, Magpul® furniture and a 15" free-float handguard. Magpul M-LOK® accessory attachment slots make the addition of a sling or bipod easy. With less recoil, and weighing almost a pound less than its .450 Bushmaster counterpart, the MPR chambered in .350 Legend is a fantastic hunting option.

Firearm Features

  • Lower receiver is fitted with Magpul® MOE® grip and MOE SL® collapsible buttstock on a Mil-Spec buffer tube.
  • Handguard is free-floated for accuracy and the slim, 15" length provides enhanced ergonomics.
  • Bolt is mil-spec 9310 and is machined and shot peened for strength 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 faster lock time for improved accuracy.
  • 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.
  • Ruger® muzzle brake is a radial port design that significantly reduces felt recoil and muzzle movement. The threaded barrel allows for standard muzzle accessories to be installed.
  • Cold hammer-forged 4140 chrome-moly steel barrel with ultra-precise rifling provides exceptional accuracy, longevity and easy cleaning. Optimized feed ramp provides improved reliability, and the matte black nitrided finish provides corrosion resistance.
  • Made from aerospace-grade 7075-T6 aluminum forging, the flat top upper receiver includes a forward assist, dust cover and brass deflector, and is Type III hard coat anodized for maximum durability.
  • Bolt carrier and gas key have chrome-plated inside diameters to provide exceptional resistance to hot gases. The gas key is staked so that it will not loosen after extensive firing.
  • Pistol-length gas system provides smoother operation and reduces felt recoil.
  • Also includes: one magazine.

(5 out of 5) New to the AR 556
by from Richmond, VA on

I just purchased a AR 556 MPR 350 Legend too hunt deer, hog and coyotes with. What a nice scope that I can put on it that's reasonable in price and also what grain bullets do you'll reccomend I'm planning on purchasing a few 20 round clips.

(5 out of 5) So far a good platform for the 350 Legend.
by from Albion, MI on

I've got 80 rounds through and it is fun to shoot. Performance is a 4 out of 5 right now`;` I had around 10 145g FMJ Winchester rounds short stroke. I am inclined to think it is an issue with the ammo and not the gun though, I will find out once I get some of the 124g Browning rounds. If this is the case itll be a 5 across the board. Was able to get a 2 group with a 50 year old Bushnell sportview scope shooting without a rest firing the Winchester FMJ plinking rounds. Id say thats not bad considering I am way out of practice and this is my first AR platform gun. If you're looking for a deer/hog gun thats fun to shoot I don't think you can go wrong with this one.

(5 out of 5) Great gun!
by from Olivet, MI on

Performs perfectly! Needed about 50 rounds to break in the bolt. It’s machined tightly. I have 120 rounds through it and the bolt is now feeding perfectly. Such a great inexpensive large round! So much fun to shoot! And that trigger!! Wow, the trigger is light, clean and crisp! Just can’t beat the value! I bought mine when it was @ $720. Looks like I bought at the right time! Can’t wait to put down some deer. Until then I will be quite happy exploding cinderblocks with my friends in the backyard! Thank you Ruger!!!
