P2A PATRIOT 10.5" 300 Blackout 1/7 or 1/5 Pistol Length Melonite M-LOK Pistol

Product Description

Optimize your intermediate distance ballistics, velocity performance, and close-quarters adaptability on a highly maneuverable AR pistol platform. The P2A PATRIOT 10.5" 300 Blackout Pistol Length Melonite Pistol is carefully engineered out of the factory to maximize powder burn efficiency for the .300 AAC Blackout cartridge while maintaining an agile handling profile. Built on matching forged 7075-T6 aluminum receiver assemblies with precise right-side ejection profiles, this platform anchors on an optimized 10.5-inch 4150 CMV medium profile barrel. The user-selectable twist matrix offers a versatile standard 1:7 twist profile for general purpose supersonic handling, or a specialized fast 1:5 twist profile engineered to stabilize heavy-grain defensive subsonic projectiles out of shorter barrel configurations. Utilizing a finely tuned pistol-length direct impingement gas setup to maximize cycling reliability, this system comes paired with a premium mil-spec bolt carrier group, lower parts completion assembly, and standard pistol buffer framework. Housed inside a rigid 9-inch free-float M-LOK handguard for clean modular integration, this complete American-made pistol delivers rugged tactical readiness right out of the box.

Key Features

  • Optimized 10.5-Inch Muzzle Core: Balances optimal complete powder combustion metrics with compact maneuverability to secure high kinetic energy levels downrange.
  • Proven Pistol-Length Gas Operation: Calibrated to maximize extraction metrics and sustain a smooth, uniform mechanical cycle under short-barrel timing dynamics.
  • Flexible Twist Rate Matrix: Select from standard 1:7 twist handling or a specialized fast 1:5 twist profile tailored explicitly to stabilize heavy subsonic grains.
  • Resilient Free-Float M-LOK Architecture: Premium 9-inch slim profile aluminum rail isolates the barrel from external handling pressure vectors, ensuring continuous point-of-impact accuracy.
  • Liquid Bath Nitride Protection: Full interior and exterior QPQ Melonite barrel treatment yields outstanding defense against heat friction, moisture elements, and throat erosion.
