P2A PATRIOT 10.5" 350 Legend 1/16 Pistol Length Melonite M-LOK Pistol

The Premium Straight-Walled Power Platform Balancing Close-Quarters Handling and High-Impact Ballistics

Step up to a specialized tactical and hunting powerhouse engineered to bring heavy intermediate straight-walled performance into an agile, compact AR footprint. The P2A PATRIOT 10.5" 350 Legend Pistol Length Melonite M-LOK Pistol is a fully assembled, factory function-tested complete firearm built to deliver maximum downrange terminal velocity and structural reliability right out of the box. While standard custom rifle-caliber builds frequently suffer from extraction errors or violent bolt travel in short configurations, this model cleanly resolves every classic engineering hurdle. By pairing a precision 10.5-inch 4150 CMV steel barrel with a custom-tuned pistol-length gas operating system, it balances optimal pressure metrics with structural component longevity. Chambered in the universally trusted, straight-walled 350 Legend caliber, this platform maximizes energy transfer and meets legal straight-walled hunting requirements within compact parameters. Featuring a lightweight free-float M-LOK rail and robust lower parts execution, this turnkey AR pistol completely eliminates assembly stress and building frustrations. Proudly 100% designed, machined, and precision-assembled in the USA with a Pro2A Tactical Lifetime Factory Warranty.

Key Features

  • Turnkey Factory Assembled Pistol: Skip the parts matching phase. This complete big-bore tactical pistol configuration ships fully assembled and tested, combining high-grade upper and lower receivers with premium internal controls.
  • Straight-Walled Hunting Compliant: Harnesses the advanced design constraints of the 350 Legend cartridge, granting hunters a compact weapon system that satisfies strict straight-walled municipal laws without carrying an oversized rifle structure.
  • Melonite/Nitride Barrel Protection: The heavy-duty 4150 CMV steel barrel undergoes an advanced Salt Bath Melonite hardening process inside and out. This treatment vastly extends bore life against rapid gas port erosion and harsh outdoor moisture, outperforming traditional chrome lining in accuracy retention.
  • Standardized 1:16 Twist Rate: Precision button-rifled with a versatile 1:16 twist rate configuration engineered to perfectly stabilize standard and heavy-duty 150-grain to 180-grain+ straight-walled hunting and tactical projectiles.
  • Slim Profile Free-Float M-LOK Rail: Crafted from premium 6061-T6 aluminum, the free-float rail isolates barrel vibrations to preserve uniform mechanical accuracy while offering extensive modular real estate for optics, sights, and tactical accessories.

Why Choose This Product?

The P2A PATRIOT 10.5" 350 Legend M-LOK Pistol directly solves the most common technical issues encountered with standard custom straight-walled rifle builds: feeding angle hang-ups, erratic casing ejection, and part-by-part tolerance stacking. When constructing specialized intermediate hunting pistols from mismatched manufacturers, builders frequently fight failure-to-feed geometry or gas timing headaches due to inconsistent feed ramp tracking and irregular gas ports. Pro2A Tactical completely eliminates these engineering frustrations by headspacing, aligning, and function-testing the entire operating block as a single unit, ensuring that the bolt, barrel extension, gas port, and buffer system interface flawlessly right out of the box.

Furthermore, choosing a 10.5-inch barrel optimized for the 350 Legend cartridge strikes the ultimate operational sweet spot for maximum close-quarters maneuverability and hard-hitting tactical flexibility. Originally engineered to deliver devastating short-to-medium range kinetic energy without forcing shooters into a bulky, heavy large-frame chassis, this firearm excels downrange. Paired here with a fast 1:16 twist rate and a custom pistol gas operating layout, it processes heavy cycling steps cleanly, tames felt muzzle rise, and handles hunting and sporting applications with ease.
