PRO2A LEFT HAND 5" 300 Blackout 1/5 Micro Length Melonite M-LOK AR-15 Upper with Flash Can Kit

Product Description

Build the ultimate compact, hard-hitting Personal Defense Weapon (PDW) layout without compromising your ergonomics. The PRO2A LEFT HAND 5" 300 Blackout Upper Kit with Flash Can delivers premium ultra-short performance engineered natively from the ground up 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 brass safely away from your face. The micro-length 5-inch barrel is paired with a super-fast 1:5 twist rate to maximize rotational stability for heavy subsonic loads, while the recessed slimline flash can drives explosive noise and concussion vectors straight downrange.

Key Features

  • True Left-Hand Architecture: Dedicated left-side ejection layout eliminates facial gas blowback and crossing casing paths for left-handed operators.
  • Ultra-Fast 1:5 Twist Rate: Engineered specifically to stabilize heavy subsonic hunting and defensive projectiles out of a micro barrel length, preventing keyholing.
  • Forward-Directing Slimline Flash Can: Mitigates severe close-quarter muzzle blast by routing concussive acoustics and pressure vectors forward and away from the shooter's ears.
  • Extended 7-Inch M-LOK Rail: Precision aluminum handguard completely encloses the flash can for a clean, continuous grip profile and reliable accessory mounting space.
  • 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.
