The Ruger AR-556 MPR in 350 Legend. A Rugged Powerhouse. 


In the vast landscape of firearms, Ruger has carved a niche renowned for rugged reliability, and now, it unveils a masterpiece in the form of the AR 556 MPR chambered in 350 Legend. This legendary caliber, coupled with Ruger's robust design, promises an unparalleled experience for hunters, outdoor enthusiasts, and survivalists alike.


This marvel starts with a lower receiver adorned with Magpul® MOE® grip and MOE SL® collapsible buttstock, ensuring ergonomic excellence and comfort during extended outings. The free-floated handguard, spanning a sleek 15 inches, not only enhances ergonomics but also guarantees pinpoint accuracy, vital for hitting targets with precision.


The backbone of any rifle is its bolt, and Ruger spares no expense in outfitting the AR 556 MPR with a mil-spec 9310 bolt, meticulously machined, shot peened, and proof tested for unmatched strength and durability. Complementing this is the Ruger® Elite 452® AR-Trigger, a two-stage trigger that delivers a smooth, crisp 4.5-pound pull, enhancing accuracy and control with every shot. The importance of a good trigger cannot be overstated, especially coming stock. Yes, mil-spec triggers work fine. But a precision trigger allows for precision trigger manipulation and this is key to precise shot placement. A great addition by Ruger. 


The integration of Magpul® M-LOK® accessory attachment slots offers versatility in customization, allowing users to personalize their firearm to suit their preferences. Meanwhile, the Ruger muzzle brake, with its radial port design, diminishes felt recoil and muzzle movement, ensuring a comfortable shooting experience even during prolonged use. And with the formidable .350 Legend coming out of the barrel, you're going to appreciate this muzzle device even more. 


Crafted from cold hammer-forged 4140 chrome-moly steel, the barrel boasts ultra-precise rifling, guaranteeing exceptional accuracy, longevity, and effortless maintenance. The optimized feed ramp enhances reliability, while the matte black nitride finish provides superior corrosion resistance, making the AR 556 MPR a reliable companion in any environment. This is great for hunting, hiking and duty use where harsh elements must be endured. 


The upper receiver, constructed from aerospace-grade 7075-T6 aluminum forging, is not only durable but also features essential components such as a forward assist, dust cover, and brass deflector. The Type III hard-coat anodized finish ensures maximum resilience against wear and tear, further solidifying Ruger's commitment to quality craftsmanship.


The pistol-length gas system enhances operation, reducing felt recoil and providing smoother shooting, even under strenuous conditions. Chrome-plated inside diameters of the bolt carrier and gas key offer exceptional resistance to hot gases, ensuring reliability with every trigger pull.


With its unrivaled performance and Ruger's sterling reputation for crafting dependable firearms, the AR 556 MPR in 350 Legend emerges as the quintessential outdoor companion. Whether for hunting, hiking, or survival scenarios, this rifle stands as a testament to Ruger's dedication to excellence, offering enthusiasts a formidable tool worthy of their adventures.


Ruger once again raises the bar with the AR 556 MPR, combining legendary caliber with unmatched reliability and precision engineering. It's not just a rifle; it's a symbol of excellence, ready to conquer the great outdoors and exceed expectations with every shot fired.
