PRO2A LEFT HAND 14.5" 5.56 NATO 1/7 Mid Length Melonite M-LOK AR-15 Upper Kit - Pinned & Welded

Product Description

Get the tight handling of a shorter carbine package combined with full structural street legality. The PRO2A LEFT HAND 14.5" 5.56 NATO Upper Kit features an extended muzzle device permanently pinned and welded to the barrel threads, bringing the overall length past the legal 16-inch mark to keep you entirely clear of NFA registration or pistol brace hurdles. Purpose-built natively from the ground up for left-handed operators, this system eliminates cross-body brass throwing and facial gas blowback via its mirrored left-ejecting receiver profile and dedicated left-hand M16 bolt carrier group. The 14.5-inch 4150 CMV barrel operates on a smooth mid-length gas configuration to drop internal pressures and dramatically mitigate felt recoil. Paired with a complete lower completion setup, this turn-key package streamlines your entire project.

Key Features

• Street-Legal Pinned & Welded Configuration: Extended flash hider or muzzle break is permanently attached to the 14.5-inch barrel to satisfy federal 16-inch minimum requirements without requiring an NFA tax stamp.
• True Left-Hand Architecture: Dedicated mirrored left-ejection port setup keeps hot casings, structural debris, and aggressive gas blowback away from your face.
• Optimized Mid-Length Cycling: Smoother gas curve reduces internal port pressure and cycling speed, softening recoil behavior while reducing structural component wear.
• Premium QPQ Melonite Protection: Liquid-nitride hardened 4150 Chrome Moly Vanadium steel barrel provides severe corrosion resistance and extended throat lifespan.
• Turn-Key Rifle Build Setup: Features a complete lower parts kit and a standard adjustable rifle stock assembly—eliminating the headache of sourcing piecemeal southpaw components.

Why Choose This Product?

The 14.5-inch pinned and welded layout remains the premier option for shooters demanding maximum maneuverability on a defensive carbine without accepting the legal limitations of a pistol brace or short-barreled rifle classification. By matching true left-handed mechanical cycling with an all-inclusive rifle-length stock build bundle, Pro2A Tactical removes the structural confusion from custom builds, ensuring southpaw shooters can step up to premium performance safely and comfortably.
