Step up to an intermediate defensive and hunting powerhouse engineered to maximize downrange terminal velocity and structural reliability without upgrading to a heavy, oversized AR-10 platform. The P2A PATRIOT 20" 350 Legend Carbine Length Melonite M-LOK Rifle is a fully assembled, factory function-tested complete firearm built to deliver maximum downrange terminal velocity and mechanical stability right out of the box. While shorter intermediate platforms compromise kinetic impact and bullet drop margins at extended ranges, this model pairs a precision full-length 20-inch 4150 CMV steel barrel with the advanced chamber dynamics of the straight-walled 350 Legend cartridge. Originally engineered to elevate intermediate hunting performance, this caliber achieves peak velocity thresholds and complete powder efficiency in longer barrel profiles, providing substantial energy footprint expansion, superior terminal energy, and flat trajectory paths. This high-velocity core is driven by a rugged, finely tuned carbine-length gas operating system optimized to handle straight-walled pressure curves, ensuring consistent chamber metrics, smooth case extraction, and reliable cycling. Featuring a lightweight free-float M-LOK rail and robust lower parts execution, this turnkey AR rifle completely eliminates building stress. Proudly 100% designed, machined, and precision-assembled in the USA with a Pro2A Tactical Lifetime Factory Warranty.

Choosing a 20-inch barrel optimized for the 350 Legend cartridge strikes the ultimate operational sweet spot for maximum downrange muzzle velocity and flat-shooting capability. Originally engineered to improve upon the hunting boundaries of smaller calibers without forcing shooters to jump into a heavy, oversized AR-10 chassis, this firearm excels downrange. Paired here with an optimized carbine-length gas operating system, it processes straight-walled pressure curves cleanly, broadening dwell timing just enough to ensure stable extraction cycles while retaining a standard rifle configuration that feels instantly familiar and comfortable to handle.
