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

Product Description

Achieve the absolute shortest legal rifle blueprint possible without administrative ATF delays or NFA tax stamp requirements. The PRO2A 13.7" 5.56 NATO Mid Length Upper Kit with Flash Can features an extended slimline flash can permanently pinned and welded to the muzzle threads, successfully stretching the physical measurement past the federal 16-inch minimum threshold. Operating on a smooth mid-length direct impingement setup, this system drops gas port velocities to deliver remarkably flat, reliable shooting dynamics. The recessed flash can routes all high-pressure muzzle blast and acoustic shockwaves straight downrange away from your ears, while the extended 15-inch free-float handguard wraps cleanly around the assembly to provide a seamless grip. Arriving alongside a complete lower components package and a rifle stock, this turn-key kit transforms your standard stripped lower receiver into an elite, legally non-NFA defense carbine.

Key Features

• Non-NFA Pinned & Welded Compliance: An extended muzzle flash can is permanently attached down to the 13.7-inch barrel threads, guaranteeing an overall rifle legal measurement of 16.1 inches without short-barreled rifle registration.
• 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.
• Optimized Mid-Length Cycling: Tuned gas curve operates at lower internal port pressures to soften bolt carrier group impact, dropping felt recoil and prolonging system lifespan.
• All-In-One Complete Assembly Setup: Saves you from individual component matching; arrives with a complete lower parts conversion kit and a non-braced rifle stock assembly.

Why Choose This Product?

A 13.7-inch pinned and welded configuration represents the ultra-compact sweet spot for intermediate rifle platforms, yielding a noticeably tighter turning radius than standard 16-inch models while remaining legally clear of NFA limitations. By matching this compact profile with a blast-directing flash can and an all-inclusive rifle stock bundle, Pro2A Tactical supplies a premium, American-made building experience that optimizes maneuverability and downrange terminal performance.
