PRO2A 16" 5.56 NATO 1/7 NR Side Charging Melonite M-LOK AR-15 Upper with Flash Can Kit
Product Overview
The PRO2A 16" 5.56 NATO 1/7 NR Side Charging Melonite M-LOK AR-15 Upper with Flash Can Kit offers a comprehensive, all-in-one upgrade package that brings advanced rifle ergonomics and maximum firing comfort to America's favorite caliber footprint. Anchored by a 16-inch 4150 CMV barrel treated with a rugged Melonite finish, this complete system optimizes velocity and mid-range performance with the 5.56x45mm NATO cartridge. Featuring a premium Non-Reciprocating (NR) side-charging handle for intuitive manual weapon manipulation and an integrated blast-directing muzzle flash can, this conversion package includes the bolt carrier group and full lower build components to drop directly onto any mil-spec lower receiver.
Key Features
Non-Reciprocating Side Charging handle: The manual side charging lever remains entirely stationary during active firing sequences, preventing visual distractions and clearing room for oversized optics.
Blast-Directing Muzzle Flash Can: Expertly forces expanding muzzle gases, concussive pressure waves, and flash signatures straight forward, shielding the shooter and team members.
Heavy-Duty Melonite Barrel finish: Liquid QPQ Nitride treatment yields an exceptionally hard, low-friction surface finish for increased barrel longevity and harsh field element protection.
Versatile 1/7 Twist Rate: Precision-stabilized button rifling dialed in to perfectly handle a vast range of standard to heavy-grain 5.56 NATO and .223 Rem projectiles.
All-In-One Conversion Kit: Arrives completely configured with a side-charging Bolt Carrier Group (BCG), free-float M-LOK rail system, lower parts matrix, and rear stock buffer components.
