Product Description

Construct a hard-hitting, reliable close-quarters configuration without sacrificing standard ergonomic safety. The PRO2A LEFT HAND 8.5" 300 Blackout Upper Kit with Flash Can offers a tailored solution built from the ground up natively for left-handed operators. Utilizing a mirrored left-ejecting receiver profile and a matching left-hand M16 bolt carrier group, this complete package routes hot gases and spent casings safely down the left side, keeping your line of sight completely clear. The 8.5-inch medium profile barrel optimizes velocity for the versatile 300 Blackout round, while the recessed slimline flash can drives hard muzzle blast and concussion vectors directly downrange. Combined with an all-inclusive lower receiver conversion kit, this package simplifies your entire custom build project.

Key Features

  • True Left-Hand Architecture: Dedicated left-side ejection layout eliminates facial gas blowback and crossing casing paths for left-handed operators.
  • Forward-Directing Slimline Flash Can: Tames harsh muzzle blast from a shorter barrel configuration, pushing severe acoustics and concussive energy safely downrange.
  • Extended 9-Inch M-LOK Rail: Precision aluminum handguard completely encloses the flash can for a clean, continuous grip profile and reliable accessory mounting space.
  • Deep Melonite Hardening: Premium 4150 Chrome Moly Vanadium barrel treated with QPQ Nitride inside and out for maximum wear protection and precision longevity.
  • Turn-Key Lower Completion Package: Arrives with a complete fire control lower build kit and an adjustable stabilizing blade assembly to streamline your entire project.

Why Choose This Product?

The 300 Blackout cartridge delivers remarkable intermediate kinetic energy out of a compact footprint, but running standard right-handed short uppers sends concussive blast right toward a southpaw shooter's face. Pro2A Tactical eliminates this hazard entirely. By matching true left-handed mechanics with an extended 9-inch handguard and forward-directing flash can setup, this complete, American-made kit yields a safe, stable, and highly capable defensive platform.
