PRO2A 16" 22LR 1/16 Rimfire Melonite M-LOK Upper with Flash Can

Product Description

Maximize your training efficiency, target precision, and cost-effective firearm manipulation with an aggressively styled rimfire assembly. The PRO2A 16" 22LR Rimfire Upper Assembly with Flash Can is meticulously engineered to unlock full-length .22 Long Rifle performance while projecting signature forward-directed blast acoustics. Unlike standard centerfire setups running finicky chamber adapters, this standalone platform utilizes an exact-spec rimfire chamber and barrel grouping to provide superior projectile stabilization and flawless cyclical reliability. Built around a premium slick-side billet upper receiver, this system encloses its 16-inch barrel and linear flash can inside an extended 15-inch free-floating M-LOK aluminum handguard. This configuration cleanly recesses the muzzle device, directing operational sound and air shock entirely forward away from the shooter while offering extensive real estate for tactical optic layouts, weapon lights, or training switch arrays.

Key Features

Clean Recessed Flash Can Aesthetics: Integrated extended linear flash can sits cleanly inside a longer 15-inch handguard profile, driving operational sound, carbon residue, and concussive shock waves straight downrange.
Full-Length 16-Inch Velocity Profiles: Maximizes powder burn efficiency on premium and bulk rimfire cartridges, providing extended downrange trajectories and superior grouping parameters over shorter pistol configurations.
Dedicated Rimfire Blowback Efficiency: Bypasses gas blocks and tubes entirely, using a reliable blowback bolt design that runs cooler and requires far less carbon maintenance through high-volume training cycles.
Resilient Free-Float M-LOK Architecture: Premium slim profile aluminum rail isolates the barrel from external handling pressure vectors, ensuring continuous point-of-impact accuracy.
Liquid Bath Nitride Hardening: The 4150 Chrome Moly Vanadium steel core features full interior and exterior QPQ Melonite coating to offer absolute weatherproofing and simple carbon cleanup.
100% Sourced & Assembled in the USA: Sourced and built to tight manufacturing metrics in Georgia, backed completely by premium custom-shop engineering quality parameters.
