PRO2A LEFT HAND 16" 223 Wylde (223/5.56) 1/7 or 1/8 Mid Length Melonite M-LOK AR-15 Upper

Product Description

Experience match-grade precision without sacrificing the rugged multi-load capability of a tactical carbine, tailored natively for left-handed operators. The PRO2A LEFT HAND 16" 223 Wylde Mid Length Melonite M-LOK Upper Assembly features a hybrid 223 Wylde chamber, precision-engineered to safely handle both higher-pressure 5.56x45mm NATO and commercial .223 Remington factory loads with tightened internal tolerances. Utilizing a mirrored left-ejecting receiver profile and a matching left-hand M16 bolt carrier group, this system completely removes cross-body brass throwing and facial carbon gas blowback common when lefties run traditional right-handed platforms. Built around a premium forged 7075-T6 aluminum receiver with m4 feed ramps, this complete upper receiver houses a 16-inch 4150 CMV medium contour barrel. Available in your choice of an ultra-stable 1:7 twist for heavy match bullets or a versatile 1:8 twist for all-purpose grain weights, this upper is tailored to your exact application.

Key Features

• True Left-Hand Ejection Architecture: Dedicated mirrored port arrangement completely eliminates cross-body brass throwing and concussive facial blowback for southpaw operators.
• Hybrid 223 Wylde Chambering: Precision dimensions maximize downrange projectile stabilization and throat accuracy bounds across both 5.56 NATO and .223 Rem payloads.
• Custom Twist Selection (1:7 or 1:8): Tailor your tracking requirements; choose 1:7 to stabilize heavy 69gr to 77gr match loads, or select 1:8 as the perfect all-grain sweet spot for standard 55gr up to precision weights.
• Soft-Cycling Mid-Length Gas Layout: Promotes extended dwell time windows to dramatically lower internal pressure peaks, soften felt recoil, and minimize component wear.
• Liquid Bath Nitride Protection: Full interior and exterior QPQ Melonite barrel coating provides maximum resistance to heat friction, extreme weather elements, and throat erosion.

Why Choose This Product?

Traditional 5.56 NATO chambers often sacrifice fine precision margins, while strict .223 Rem chambers cannot handle higher NATO case expansion variables—and running standard right-handed setups forces unmanaged gas blowback directly across a left-handed operator's face. Pro2A Tactical bridges this divide perfectly with the 223 Wylde chamber profile. By pairing this optimized hybrid chamber with precision twist rate optionality, a mirrored left-ejection port system, and a robust Melonite treatment, this American-made upper receiver delivers sub-MOA precision thresholds alongside absolute face-safe field reliability.
