Ruger AR-556 MPR Pistol in 350 Legend: The Ultimate Compact Powerhouse for Hunters and Shooters

Are you searching for a compact, powerful, and exceptionally reliable AR-platform firearm designed to excel in diverse shooting scenarios, particularly in areas requiring straight-wall cartridges for hunting? Look no further than the Ruger AR-556 MPR Pistol chambered in the potent Winchester 350 Legend. This modern sporting pistol is engineered to meet the stringent demands of serious hunters, sport shooters, and those seeking a robust solution for personal defense, offering a potent blend of performance, precision, and proven Ruger reliability.

The 350 Legend cartridge has rapidly gained immense popularity, especially among hunters in states like Ohio, Michigan, Indiana, Iowa, and Pennsylvania, where straight-wall cartridges are often mandated for deer and other game. Ruger’s AR-556 MPR Pistol answers the call by providing a purpose-built, highly accurate, and maneuverable platform perfectly optimized for this versatile cartridge. It's an ideal choice for hunters navigating dense woods, standing in blinds, or engaging targets from treestands, where a shorter, lighter firearm offers significant advantages without sacrificing stopping power. For recreational shooters, its managed recoil and AR-15 familiarity make it a joy to shoot at the range, while its compact footprint lends itself well to vehicle storage or home defense applications.

Why Choose the 350 Legend Cartridge in an AR Pistol?

The Winchester 350 Legend cartridge was specifically developed to provide a powerful, low-recoil option with excellent ballistic performance, all while adhering to straight-wall cartridge hunting regulations. When paired with a compact AR pistol like the Ruger AR-556 MPR, it creates an incredibly effective tool.

• Hunting Versatility: The 350 Legend delivers ample energy for medium-sized game like deer and hogs, even from a shorter barrel. Its flatter trajectory compared to many traditional pistol cartridges ensures confident shot placement out to typical hunting distances.
• Legal Compliance: For hunters in states with specific straight-wall cartridge requirements, the 350 Legend is a game-changer, opening up access to AR-platform firearms for big game hunting.
• Low Recoil: Despite its power, the 350 Legend offers surprisingly manageable recoil, which is further tamed by the Ruger AR-556 MPR Pistol’s integrated radial port muzzle brake. This makes for faster follow-up shots and more comfortable shooting sessions.
• AR-15 Compatibility: Designed to feed reliably from standard AR-15 magazines, the 350 Legend allows for seamless integration into existing AR ecosystems, leveraging the familiarity and wide array of accessories available for the platform.

Uncompromising Ruger Engineering: Features Designed for Performance

Every aspect of the Ruger AR-556 MPR Pistol is meticulously engineered to ensure peak performance, durability, and user experience. Built on the foundation of Ruger's celebrated AR-platform rifles and pistols, this model integrates advanced features that elevate it above standard offerings, ensuring it stands as a testament to Ruger's legacy of reliability and affordability.

Precision Trigger System: The Ruger Elite 452 AR Trigger

A critical component for accuracy and control, the Ruger AR-556 MPR Pistol comes standard with Ruger’s innovative Elite 452 AR Trigger. This two-stage trigger system provides a light, crisp break, significantly enhancing the shooter's ability to achieve precise shot placement. Unlike standard mil-spec triggers, the Elite 452 offers a smoother pull, reduced take-up, and a cleaner reset, which translates directly into improved accuracy whether you're taking a critical shot at a game animal or engaging targets rapidly at the range. This premium trigger contributes substantially to the overall shooting experience, making the Ruger AR-556 MPR Pistol feel like a custom-tuned firearm right out of the box.

Enhanced Stability and Recoil Management: SB Tactical SBA3 Pistol Stabilizing Brace

One of the standout features defining this firearm as a pistol, and enhancing its capabilities, is the adjustable SB Tactical® SBA3™ Pistol Stabilizing Brace®. This brace is not merely an accessory; it's an integral component designed to significantly aid in accuracy, balance, and recoil management. The SBA3 provides five positions of adjustment, allowing shooters to customize the length of pull for optimal comfort and stability. By offering a third point of contact, it helps to steady the firearm, leading to tighter groups and improved control, particularly crucial for a powerful cartridge like the 350 Legend in a compact pistol format. Its robust construction ensures reliable performance in demanding environments.

Optimized Barrel Design: Cold Hammer-Forged for Superior Performance

The heart of any accurate firearm is its barrel, and the Ruger AR-556 MPR Pistol boasts a 9.50" cold hammer-forged 4140 chrome-moly steel barrel. This manufacturing process creates a barrel with ultra-precise rifling, ensuring exceptional accuracy and remarkable longevity, even under sustained firing. The cold hammer-forging process compresses the steel, making it denser and more durable, which translates into a barrel that resists wear and maintains its accuracy over thousands of rounds.

• Reliable Feeding: Equipped with M4 feed ramps, the barrel and receiver extension work in concert to provide improved reliability, ensuring smooth and consistent feeding of 350 Legend cartridges, minimizing potential malfunctions.
• Corrosion Resistance: A matte black oxide finish on the barrel reduces glare and provides excellent corrosion resistance, protecting the firearm from the elements and ensuring its aesthetic and functional integrity for years to come.
• Muzzle Versatility: The barrel is threaded with a 1/2"-28 x 0.4 pattern, a common standard for AR-style firearms. While it ships with a Ruger® flash suppressor and a radial port muzzle brake for recoil reduction, this threading allows for easy installation of other standard muzzle accessories, including a wide array of suppressors for quieter shooting experiences, making this pistol highly adaptable to various user preferences.

Robust Construction: Aerospace-Grade Aluminum Receivers

The flattop upper receiver is crafted from aerospace-grade 7075-T6 aluminum forging, a material renowned for its exceptional strength-to-weight ratio and durability. This robust construction ensures the firearm can withstand the rigors of heavy use while remaining lightweight for maneuverability. The upper receiver includes essential features such as a forward assist for positive bolt closure, a dust cover to protect internal components from debris, and a brass deflector to safely eject spent casings away from the shooter. The lower receiver is also meticulously crafted to house the fire control group and integrate seamlessly with the SB Tactical SBA3 brace. Both receivers feature a Type III Hard Coat Anodized finish, providing a durable, corrosion-resistant surface that stands up to wear and tear.

Precision-Engineered Bolt and Carrier Group

The bolt is machined from 9310 alloy steel, a high-strength material often used in demanding applications, and is meticulously shot peened and pressure (proof) tested. This rigorous testing and treatment process ensures the bolt's strength, structural integrity, and long-term durability, providing peace of mind for the shooter. The bolt carrier and gas key feature chrome-plated inside diameters, which offer exceptional resistance to the hot gases generated during firing, contributing to the firearm's overall reliability and ease of cleaning. Furthermore, the gas key is properly staked, a critical detail that prevents it from loosening even after extensive firing, a common point of failure in lesser quality AR platforms. A matte black oxide finish on the exterior of the bolt carrier provides an additional layer of corrosion resistance.

Dependable Carbine-Length Gas System

The Ruger AR-556 MPR Pistol utilizes a carbine-length gas system, operating on the proven direct-impingement principle. This system is known for its simplicity and effectiveness, ensuring reliable function across a wide variety of ammunition types, from various bullet weights to different manufacturers. The proper tuning of this gas system contributes to the firearm's smooth cycling and consistent performance, minimizing potential stoppages and maximizing time on target.

Ergonomic and Versatile Handguard

A slim, 9" free-floating handguard ensures maximum accuracy by preventing any external pressure from affecting the barrel's harmonics. This design also provides enhanced ergonomics and support for the shooter, allowing for a comfortable and secure grip. The handguard is equipped with Magpul® M-LOK® accessory attachment slots along the 3:00, 6:00, and 9:00 positions, offering ample real estate for mounting lights, lasers, bipods, and other essential accessories, allowing for extensive customization to suit individual needs and mission requirements.

Ready for Action: Included Accessories

The Ruger AR-556 MPR Pistol comes ready for action right out of the box, including one 5-round Magpul® PMAG® magazine. Magpul PMAGs are renowned for their reliability, durability, and robust construction, providing a trusted feeding source for this potent pistol.

Ideal Applications for the Ruger AR-556 MPR Pistol

This versatile firearm is perfectly suited for a multitude of applications, making it a valuable addition to any shooter's collection.

• Deer and Hog Hunting: Especially in states with straight-wall cartridge regulations, the 350 Legend coupled with the compact, maneuverable AR pistol platform makes it an outstanding choice for hunting medium game in dense cover.
• Recreational Shooting and Target Practice: The manageable recoil, excellent ergonomics, and crisp trigger make it incredibly enjoyable for extended range sessions. Its accuracy potential allows shooters to hone their skills effectively.
• Home Defense and Personal Protection: The compact size of the pistol makes it highly maneuverable in close quarters, while the stopping power of the 350 Legend cartridge provides substantial deterrent capability. The ability to attach lights and other tactical accessories further enhances its utility in defensive scenarios.
• Vehicle or Backpack Gun: Its overall length and lighter weight make it an excellent choice for a "truck gun" or for discreet transport where a full-sized rifle might be cumbersome.
