PRO2A 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. The PRO2A 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. Configured on a precision forged 7075-T6 aluminum receiver with strict right-side ejection metrics, this complete assembly utilizes 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. Operating on a smooth direct impingement mid-length gas system to ensure low operating port pressures and comfortable cycling, this turn-key platform drops seamlessly onto any standard AR-15 lower receiver.

Key Features

• 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.
• Resilient Free-Float M-LOK Handguard: Premium 15-inch slim profile aluminum rail isolates the barrel from external handling pressure vectors, ensuring continuous point-of-impact accuracy.

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. Pro2A Tactical bridges this divide perfectly with the 223 Wylde. By pairing this optimized hybrid chamber with precision twist rate optionality, a smooth mid-length gas system, and a robust Melonite treatment, this American-made complete upper receiver delivers sub-MOA precision thresholds alongside absolute battle-ready reliability.
