PRO2A 10.5" 7.62x39 1/10 Carbine Length NR Side Charging Melonite AR-15 Upper Kit with Flash Can
Complete Master Build Bundle with Non-Reciprocating Ergonomics, Enhanced Ignition, and Concussion Control
Bring the heavy-hitting ballistics of the classic 7.62x39mm cartridge to a modern, highly ergonomic platform with the PRO2A 10.5" Non-Reciprocating (NR) Side Charging M-LOK Upper Kit with Flash Can. This 100% American-made master build bundle contains every critical component required to transform a standard stripped lower receiver into a finished tactical pistol or short-barreled rifle. Engineered to eliminate the historical ignition and manual layout bottlenecks of this caliber on the AR frame, it shifts the cocking action to a stationary, left-side handle for uninterrupted optic clearance. Equipped with an integrated blast-forward Flash Can tucked inside a modular free-float M-LOK rail, a complete lower parts kit (LPK), and a matching pistol stabilizing blade assembly, this package delivers seamless out-of-the-box performance without individual part tuning.
Key Features:
- All-In-One Master Pistol Package: Eliminates technical tracking hurdles by bundling the side-charging upper, tucked linear flash director, enhanced 7.62x39mm bolt group, full lower internal hardware, and matching pistol blade setup together.
- Non-Reciprocating Left-Side Handle: The side charging handle remains completely stationary while the weapon fires, shielding your support hand and letting you run the action fluidly without breaking your sight picture.
- Blast-Forward Linear Flash Can: Pre-installed muzzle device redirects intense short-barrel gas expansions, sound waves, and concussive reports directly downrange—maximizing comfort during close-quarters operation.
- Enhanced Firing Reliability: Outfitted with an optimized side-charging 7.62x39mm Bolt Carrier Group utilizing an extended, enhanced firing pin and a tailored bolt face to guarantee consistent primer ignition on hard steel-cased surplus ammunition.
- Advanced Melonite Barrel Protection: Premium 4150 CMV steel barrel is fully treated with an advanced Salt Bath Melonite finish inside the bore and across the exterior to extend service life and offer total protection against moisture and wear.
- Pistol Blade & LPK Hardware Included: Complemented by a high-strength stabilizing blade extension and a complete, unified lower parts layout to wrap up your entire defensive build smoothly.

Why Choose the PRO2A 7.62x39 Flash Can Master Kit?
Piecing together an AR pistol build in 7.62x39mm manually often exposes builders to light primer strikes on surplus steel ammo, gas configuration errors, and brutal blast concussion on short barrels. The PRO2A 10.5" Master Kit solves all three vulnerabilities right out of the box. By matching a pre-headspaced side-charging bolt group containing an extended enhanced firing pin with a heavy buffer system, it delivers flawless cycling on affordable ammunition.
Tucking the linear flash can cleanly inside the extended free-float handguard protects accessories while channeling concussive pressure safely away from the operator. With a fluid left-side charging handle that completely isolates manipulation from mounted optics, this comprehensive bundle provides duty-grade reliability in an optimized, budget-friendly package.
