Product Description

The PRO2A Left Hand 12.5" 5.56 NATO Carbine Length Melonite M-LOK Upper Kit with Flash Can delivers a highly optimized short-barreled completion package engineered specifically for left-handed operators building a versatile defensive pistol or SBR with superior terminal ballistics. To tame the raw blast concussion typical of shorter 5.56 configurations, this platform features a linear muzzle device recessed beneath an extended handguard rail, safely routing concussive energy downrange away from the shooter's support hand. Complete with a true left-ejecting forged receiver, dedicated left-handed bolt carrier group, full lower parts completion kit, and adjustable stock assembly, it supplies southpaw builders with a seamless path to finalize their custom build.

Key Features

• True Left-Hand Port Configuration: Mirrored left-ejection path routes scorching expansion gases and empty shell debris cleanly away from a left-handed shooter's face and eyes.
• Blast-Forwarding Linear Flash Can: Mitigates harsh lateral concussive waves, combustion blast pressure, and intense muzzle flash by forcing them completely forward downrange toward your targets.
• All-In-One System Completion: Bundles your high-accuracy intermediate upper assembly with a specialized left-hand BCG, standard charging handle, complete lower parts kit, and an adjustable stock conversion package.
• Optimized 12.5" Dwell Time: Combines a reliable carbine-length gas port configuration with a 12.5-inch barrel blueprint to offer vastly improved velocity profiles and cleaner cycling stability compared to shorter micro formats.
• Premium Melonite Structural Defense: Heavy-duty 4150 CMV steel is thoroughly liquid nitrided to secure supreme environmental corrosion resistance and a longer bore throat life.
