PRO2A LEFT HAND 13.7" 5.56 NATO 1/7 Mid Length NR Side Charging Melonite M-LOK AR-15 Upper with Flash Can Kit - Pinned & Welded

Product Description

Experience premium southpaw ergonomics, rapid cycling manipulation, and the absolute shortest legal rifle blueprint possible without NFA tax stamp requirements. The PRO2A LEFT HAND 13.7" 5.56 NATO Non-Reciprocating (NR) Side Charging Upper Kit with Flash Can completely transforms the AR-15 platform by pairing a true left-ejecting action with a smooth side-charging handle that remains static during firing cycles. An extended slimline flash can is permanently pinned and welded to the muzzle threads, successfully stretching the physical barrel length past the federal 16-inch minimum threshold. Operating on a tuned mid-length direct impingement setup, this configuration dramatically cuts down on felt recoil and cyclic port pressures while routing aggressive gas blowback safely down the left side. The recessed flash can directs high-pressure muzzle blast and acoustic shockwaves straight downrange, while the 15-inch free-float M-LOK handguard provides a continuous, clean gripping surface. Complete with all lower receiver completion components and a rifle stock assembly, this turn-key package upgrades your stripped lower into an elite defensive carbine.

Key Features

• True Left-Hand Architecture: Dedicated mirrored left-ejection port setup keeps hot casings, structural debris, and aggressive gas blowback completely away from left-handed operators.
• Non-Reciprocating Side Charging Handle: Side charging mechanism permits fast weapon charging while keeping your eyes fixed on target and remains entirely stationary when cycling.
• Street-Legal Pinned & Welded Configuration: Extended muzzle flash can is permanently attached down to the 13.7-inch barrel threads, ensuring an overall rifle legal measurement of 16.1 inches without short-barreled rifle registration or ATF delays.
• Forward-Directing Slimline Flash Can: Significantly tames the concussive muzzle punch and intense side-blast typical of shorter carbines by managing acoustic pathways forward.
• Extended 15-Inch M-LOK Handguard: The free-floating aluminum rail cleanly encompasses the recessed flash can layout, offering maximum mounting real estate for optics, lights, and laser setups.
• Turn-Key Lower Completion Package: Saves you from individual component matching; arrives with a complete lower parts conversion kit and a non-braced rifle stock assembly.
