PRO2A Left Hand 13.7" 5.56 NATO NR Side Charging Melonite Upper Kit
PRO2A LEFT HAND 13.7" 5.56 NATO 1/7 Carbine Length NR Side Charging Melonite M-LOK AR-15 Upper Kit
Product Overview
The PRO2A LEFT HAND 13.7" 5.56 NATO 1/7 Carbine Length NR Side Charging Melonite M-LOK AR-15 Upper Kit establishes a masterclass in modern, compact agility for southpaw shooters. Purpose-built to achieve a highly desirable "recce" style layout, this premium platform pairs a true left-handed ejection architecture with a high-leverage **Left-Side Non-Reciprocating (NR) side-charging handle**. This geometry blocks toxic gas blowback and high-speed spent casings away from left-dominant vision paths. Featuring a precision 13.7-inch Melonite-treated barrel with a match-preferred 1/7 twist rate, it serves as an exceptional foundation for pin-and-weld projects to clear standard length requirements or NFA layouts. Bundled comprehensively with a true left-hand nitride BCG, complete lower parts kit, and an adjustable stock assembly, it has everything needed to finalize your stripped lower.
Key Features
True Left-Handed Ejection Geometry: Purpose-built mirrored upper receiver safely ejects gas, debris, and brass to the left side, entirely protecting southpaw eyes and facial real estate.
Non-Reciprocating Side Charging Architecture: The right-side manual handle remains static during live fire sequences, allowing fast manipulations under large optics without moving elements disrupting support hands.
Matched Left-Handed Drive Group: Comes configured out-of-the-box with a true left-handed 5.56 NATO nitride bolt carrier group for crisp mechanical timing and seamless lockup.
Complete Build Completion Bundle: Ships loaded with a complete Mil-Spec lower parts assembly (fire control group, pins, springs, and pistol grip) and an M4-style six-position collapsible stock system.

Why Choose This Product?
Use code with caution.For left-handed shooters, executing transitions or cycling standard rear-charging 5.56 rifles frequently compromises cheek welds and target awareness, while exposing the face to immediate, harsh ejection port blowback. This PRO2A kit eradicates those legacy layout bottlenecks entirely. Shifting onto an advanced non-reciprocating left-side side-charger provides rapid weapon charging capabilities without any moving pieces tracking backward toward your grip. When integrated with a highly mobile 13.7" barrel profile and a total suite of lower completion components, it offers southpaws a clean, fast-handling, all-in-one rifle project with guaranteed mechanical compatibility across the board.
