PRO2A LEFT HAND 6" 300 Blackout Pistol Length NR Side Charging Melonite M-LOK AR-15 Upper with Flash Can Kit

Elite Micro PDW Upgrade Package with Left Ejection & Stationary Left Side Cocking

Construct the ultimate compact personal defense weapon (PDW) with flawless southpaw ergonomics, forward directed ergonomics, and uncompromised build execution. The PRO2A Left Hand 6" 300 Blackout Pistol Length Non-Reciprocating (NR) Side Charging Upper Assembly with Flash Can Kit is an all-inclusive, range-ready build solution that bundles a complete upper assembly with a premium matching left-handed side-charging bolt carrier group (BCG). By pairing a mirrored left-ejection port layout with an ergonomic left-side charging handle, this upper keeps hot brass and escaping blowback gases completely out of your peripheral line of sight. The non-reciprocating handle stays stationary while firing, providing a seamless operating zone free from moving external components. Pre-equipped with a slimline tactical flash can, it forces intense micro-barrel gas concussion and muzzle noise straight forward downrange away from the operator. Drops natively onto any standard left-handed or ambidextrous Mil-Spec lower receiver. Proudly 100% designed, machined, and precision-assembled in the USA.

Key Features

  • Complete Drop-In Left-Hand Integration Kit: Eliminates the hassle of headspacing and sourcing rare left-handed side-charging components. This comprehensive kit ships complete with a matching premium left-handed side-charging bolt carrier group (BCG) engineered to interface flawlessly right out of the box. Comes with everything needed to complete a stripped lower receiver.
  • Mirrored Left-Hand Port & Side Charging Layout: Specifically designed to safely redirect spent casings and concentrated powder blowback out of the left side. The stationary side lever lets you charge the system easily from prone or benched layouts, maintaining constant weapon alignment and sealing off the rear opening to block backpressure from venting into your face.
  • Integrated Slimline Flash Can: Pre-installed on the muzzle to tame the sharp acoustic blast typical of micro-barrel configurations. It acts as a linear director, projecting noise, gas, and flash away from the shooter to maximize training lane and tight-quarters comfort.
  • Ultra-Compact 6-Inch Barrel Profile: Yields the ultimate footprint optimization for quick target transitions, weapon packing, and vehicle deployment while extracting heavy .30-caliber ballistic performance out of the standard 300 AAC Blackout cartridge.
  • Melonite/Nitride Barrel Protection: The heavy-duty 4150 CMV steel barrel is fully Nitride/Melonite treated inside and out. This premium chemical hardening vastly extends barrel life against suppressed shooting carbon buildup, aids in uniform thermal dissipation, and counters harsh weather corrosion.
