Product Description

Achieve unparalleled long-range precision, optimized structural rigidity, and customized physical ergonomics with the standalone PRO2A LEFT HAND 22" 223 Wylde Rifle-Length Melonite Fluted Heavy Bull Barrel M-LOK AR-15 Upper Receiver. Engineered specifically to meet the strict demands of competitive southpaw marksmen and varmint hunters, this upper effectively eliminates right-side gas blowback and facial debris. This premium assembly features an elite 22-inch fluted heavy bull barrel that bridges the gap between .223 Remington and 5.56x45mm NATO ballistics, offering tight mechanical tolerances and maximum velocity extraction.

Key Features

• Dedicated Left-Hand Architecture: Features a mirrored left-side ejection port orientation to direct spent casings and high-pressure blowback gases away from a left-handed operator's vision.
• High-Velocity 223 Wylde Chambering: Safely shoots both .223 Remington and 5.56 NATO ammunition with a highly refined throat angle designed to maximize accuracy profile stability.
• Fluted Heavy Bull Barrel Profile: The massive bull contour eliminates barrel whip and stabilizes harmonic resonance under fast strings of fire, while aggressive longitudinal fluting reduces overall weight and accelerates cooling times.
• True Rifle-Length Gas Mechanics: Drops gas port pressure limits down to smooth operational thresholds, significantly decreasing parts wear and maintaining an incredibly soft, controllable recoil track.
• QPQ Melonite Extreme Protection: Barrel bore, chamber configuration, and exterior walls are liquid nitrocarburized to provide a slick, high-wear surface finish outperforming traditional mil-spec chrome lining.
• Rigid M-LOK Handguard: A 15-inch ultra-lightweight free-float handguard provides an uninterrupted top Picatinny rail structure and ample lateral space to prevent stress on the barrel profile.
