PRO2A 8.5" 40 S&W 1/16 Pistol Caliber NR Side Charging Melonite M-LOK Upper with Flash Can Kit

Description

The Pro2A Tactical 8.5-inch .40 S&W Non-Reciprocating (NR) Side Charging Complete Upper Kit with Flash Can delivers exceptional tactical ergonomics, advanced blast routing, and hard-hitting muzzle performance to the AR-40 platform. Assembled by hand and verified for concentricity in Georgia, this premier conversion layout integrates a rigid billet receiver that replaces the traditional rear charging handle with an advanced, static side-charger mechanism. Paired with a linear flash can that pushes muzzle blast and concussion downrange, this comprehensive build kit arrives fully populated with a matching side-charging blowback bolt group, full lower parts kit, and optimized heavy buffer stock assembly to streamline your transition into a premium weapon platform.

Key Features

• Non-Reciprocating Charging Control: Features an advanced side-charging design with a handle that remains fully static while cycling, preventing optic mount interference and maximizing mechanical leverage from standard shooting positions.
• Forward Concussion Redirection: Outfitted with a slimline aluminum linear Flash Can muzzle device that forces blast, noise, and concussive pressure downrange away from the operator.
• Turnkey Conversion Bundle: Simplifies your build process by combining a fully populated side-charging upper receiver group, tucked flash can, matched blowback BCG, complete lower parts kit (LPK) with fire control group, and a pistol blade assembly.
• Aggressive Tucked Silhouette: The linear flash can sits partially shrouded beneath the free-floating 9-inch M-LOK handguard, optimizing rail accessory real estate while establishing a flush profile.

Why Choose This Product?

Assembling a high-performance .40 S&W platform demands rigid mechanical compliance, as straight blowback layouts absorb severe cyclic chamber pressures. The Pro2A 8.5" .40 S&W NR Side Charging Upper Kit with Flash Can solves these layout limitations entirely by grouping a factory-headspaced nitrided side-charging bolt group with a forward-directing muzzle layout and an optimized heavy-weight buffer system to control recoil smoothly. Featuring a revised feed cone geometry that handles flat-nose target ammo and high-expansion defensive ammunition alike, this kit strips away common configuration headaches. It is the definitive choice for personal defense and tactical shooters seeking a premium, flat-shooting weapon system built all in one package.
