Product Description

Achieve unparalleled long-range precision, maximum muzzle velocity, and exceptional thermal management with the complete PRO2A 22" 223 Wylde Rifle-Length Melonite Fluted Heavy Bull Barrel AR-15 Upper Kit. Built specifically to meet the high-accuracy needs of varmint hunters and competitive target shooters, this master build package provides a meticulously headspaced 22-inch heavy bull barrel assembly paired with a smooth-cycling rifle gas system. Engineered as a comprehensive all-in-one build solution, this kit comes fully populated with a premium M16 profile bolt carrier group, an enhanced charging handle, a complete mil-spec lower parts kit, and a full carbine stock assembly—supplying every essential internal component required to complete your stripped lower receiver.

Key Features

• All-Inclusive Master Build Kit: Bundles the complete barreled upper receiver with a premium bolt carrier group, charging handle, full lower parts kit, and rear receiver stock hardware.
• High-Velocity 223 Wylde Chambering: Safely shoots both .223 Remington and 5.56 NATO ammunition with a highly refined throat angle designed to maximize long-range ballistic stability.
• Fluted Heavy Bull Barrel Profile: The massive bull contour eliminates barrel whip and stabilizes harmonic resonance under rapid strings of fire, while aggressive longitudinal fluting reduces overall weight and accelerates cooling times.
• Ultra-Smooth Rifle Recoil: True rifle-length direct impingement gas dynamics drop peak port pressures significantly, delivering clean cycling and an incredibly soft, predictable recoil impulse.
• QPQ Melonite Extreme Armor: Barrel bore, chamber, and exterior are fully liquid nitrocarburized to exceed mil-spec chrome lining in surface hardness, heat dissipation, and corrosion resistance.
• Slim Profile M-LOK Workspace: Features a continuous top Picatinny rail interface seamlessly blended into a 15-inch free-floating M-LOK handguard for rigid mounting stability.

Why Choose This Product?

The PRO2A 22" 223 Wylde Rifle Length Fluted Heavy Bull Barrel Kit removes the complexity of sourcing structural precision components across separate vendors by providing a perfectly headspaced and balanced ecosystem out of the box. Traditional configurations force shooters to compromise on heat buildup or wrestle with aggressive recoil impulses. By coupling an extended 22-inch precision heavy bull barrel with a rifle-length gas track, this system minimizes barrel harmonics and softens target re-acquisition times. Completely paired with an advanced M16 Nitride bolt group, an ambidextrous charging handle, a clean single-stage trigger group, and complete stock hardware, this system ensures total hardware harmony under the protection of a full Structural Lifetime Warranty.
