Pro2A 8.5" 40 S&W NR Side Charging Melonite M-LOK Upper Kit

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

Description

The Pro2A Tactical 8.5-inch .40 S&W Non-Reciprocating (NR) Side Charging Complete Upper Kit contains all the necessary components to transform a standard stripped lower receiver into an advanced, ergonomically superior pistol caliber carbine. Proudly built and inspected in Georgia, this package introduces a rigid billet receiver that replaces the traditional rear charging handle with a static side-charging mechanism. This comprehensive build kit arrives populated with a matching side-charging blowback bolt group, full lower parts kit, and heavy buffer stock assembly to ensure structural harmony out of the box.

Key Features

Non-Reciprocating Charger: Upgrades weapon manipulation with a side-mounted charging handle that stays static while firing, ensuring clearing leverage and seamless compatibility with large optics.
Turnkey Conversion Bundle: Simplifies sourcing by packaging a fully populated side-charging upper receiver group, matched blowback BCG, complete lower parts kit (LPK) with fire control components, and a full pistol blade assembly.
Blowback Action Simplicity: Engineered completely without gas blocks or gas tubes, eliminating high-wear parts to establish ultra-dependable feeding and extraction patterns.
Premium Melonite Integrity: Treated inside and out with an ultra-hard Melonite finish, maximizing barrel bore life and defending against corrosive materials while offering effortless cleanings.

Why Choose This Product?

Assembling a high-performance .40 S&W AR setup demands rigid mechanical compliance, as straight blowback actions lack the buffer delays of traditional gas systems. The Pro2A 8.5" .40 S&W NR Side Charging Upper Kit solves this layout requirement by combining a factory-headspaced nitrided bolt group with an optimized heavy-weight buffer system to control bolt velocity smoothly. Enhanced with a revised feed cone geometry that processes flat-nose target ammo and high-expansion defensive hollow points natively, this system operates flawlessly. It is the absolute pinnacle setup for competitive operators and tactical home defenders seeking a premium, flat-shooting weapon system built all in one package.
