PRO2A 5" 9mm 1/10 Pistol Caliber NR Side Charging Melonite M-LOK Upper Kit with Flash Can

Build the ultimate ultra-compact, heavy-duty defensive pistol with the PRO2A 5" 9mm 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 pistol lower receiver into a finished tactical asset. Built around an ultra-compact 5-inch 4150 CMV steel barrel, this kit features an integrated blast-forward flash can tucked cleanly inside a modular free-float M-LOK rail to project firing concussions safely downrange. Shifting the manual action to a stationary left-side location guarantees uninterrupted optic clearance. Complete with a ramped blowback bolt carrier group, a full lower parts kit (LPK), and a matching pistol buffer extension with a stabilizing blade assembly, this package bypasses individual hardware tuning to ensure smooth out-of-the-box performance.

Key Features

All-In-One Complete Pistol Package: Eliminates technical tracking hurdles by bundling the side-charging upper, tucked linear flash director, ramped 9mm blowback bolt group, full lower internal hardware, and matching pistol blade setup together.
Non-Reciprocating Left-Side Handle: The side charging mechanism remains completely stationary while the system cycles, shielding hands and ensuring smooth manual controls without breaking your sight picture or bumping low-profile red dots.
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 fast-paced close-quarters operation.
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.
Ramped Direct Blowback BCG: Gas-less operation utilizing a high-durability 9mm bolt group tailored to feed flawlessly from standard pistol caliber lower configurations and compatible Glock or Colt profile magazines.
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 Buy This Product?

Piecing together an ultra-short 9mm pistol build manually can lead to frustrating cycling failures, weak extraction, and harsh concussion due to incorrect buffer weights and gas-less blowback pressures. The PRO2A 5" 9mm Side Charging Kit directly solves these issues by packaging a specialized, heavy 9mm pistol buffer, a pre-headspaced ramped BCG, and an integrated linear blast director into a single, cohesive bundle. By shifting the charging handle to the side and including a stabilizing blade assembly and lower internal hardware, you get a fluid, highly ergonomic defense build that operates reliably out of the box. Hand-assembled and quality-tested in the USA, this complete conversion package maximizes your value while keeping the overall footprint highly packable.
