PRO2A 16" 223 Wylde 1/7 Mid Length Stainless Premium M-LOK AR-15 Upper

The Ultimate General-Purpose Carbine for Match-Grade Accuracy

Achieve the perfect balance of standard carbine mobility and exceptional downrange precision. The PRO2A 16" 223 Wylde Mid-Length Stainless Premium M-LOK Upper Assembly is engineered to deliver sub-MOA mechanical consistency in a fast-handling package. Built around a premium 416R stainless steel barrel, this complete upper receiver features the hybrid .223 Wylde chamber to safely leverage both high-pressure duty rounds and match ammunition. It drops natively onto any standard Mil-Spec AR-15 lower receiver to provide a flat-shooting tactical, hunting, or home-defense tool. Proudly 100% designed, machined, and hand-assembled in the USA.

Key Features

  • Match-Grade 416R Stainless Steel Barrel: Precision-crafted from premium 416R stainless steel, this 16-inch barrel resists aggressive physical friction and thermal spikes, guaranteeing tight group clusters and repeatable point-of-impact accuracy.
  • Versatile .223 Wylde Chambering: Engineered with the tight throat dynamics of a hybrid chamber to safely fire military-surplus 5.56x45mm NATO and commercial .223 Remington loads with significantly greater mechanical consistency over traditional 5.56 chambers.
  • Smooth Mid-Length Gas Operating System: Configured with a mid-length gas system to optimize port pressures and dwell time. This yields a noticeably softer recoil impulse, reduces internal component stress, and ensures flat muzzle tracking for faster follow-up shots.
  • Fast 1:7 Button-Rifled Twist Rate: The aggressive 1:7 twist rate provides rapid rotational stability, allowing you to flawlessly shoot heavier duty projectiles—including 62-grain and 77-grain match options—while retaining clean execution with standard target ammunition.
  • 12-Inch Free-Float M-LOK Handguard: Built from durable 6061-T6 aluminum, the slim free-float handguard eliminates barrel vibrations to preserve accuracy while offering an expansive layout for accessories and an uninterrupted top Picatinny configuration.
