PRO2A Left Hand 10.5" 5.56 NATO Carbine NR Side Charging Upper with Flash Can
PRO2A LEFT HAND 10.5" 5.56 NATO 1/7 Carbine Length NR Side Charging Melonite M-LOK AR-15 Upper with Flash Can
Product Overview
The PRO2A LEFT HAND 10.5" 5.56 NATO 1/7 Carbine Length NR Side Charging Melonite M-LOK AR-15 Upper with Flash Can brings an uncompromised tactical configuration to southpaw shooters seeking the ideal short-barreled platform. Discarding standard rear-charging designs, this complete upper receiver features an ergonomic, Non-Reciprocating (NR) left side-charging interface. True left-hand ejection geometry ensures that hot spent casings and high-pressure carbon exhaust are thrown safely away from your sightlines. To tame the raw concussive blast inherent to short 5.56 configurations, this model integrates a project-forward linear Flash Can muzzle device tucked neatly beneath its slim free-float handguard.
Key Features
True Left-Hand Architecture: Mirrored left-ejecting receiver profile paired with a matched left-hand bolt carrier group routes blinding carbon blowback and spent shells completely clear of left-dominant eyes.
Non-Reciprocating Side Charging: Fluid manual side charging handle remains completely stationary while the action cycles, giving you absolute structural clearance for optics without moving parts near your support hand.
Linear Flash Can Muzzle Device: Channels severe short-barrel muzzle blast by forcing sound pressure, thermal expansion, and concussive shock waves directly downrange and away from the operator.
Maneuverable 10.5-Inch Profile: Slashes overall length to optimize maneuvering speed in tight spaces, vehicular configurations, or dense home-defense environments.
Smooth Carbine-Length Gas System: Calibrated with a low-profile gas block to supply excellent dwell time, lowering component wear and softening the overall recoil impulse.
Fast 1/7 Twist Rifling: Precision-rifled profile engineered to provide excellent rotational stabilization for popular heavy grain tactical and mil-spec projectiles (62gr, 69gr, and 77gr).
QPQ Melonite Hardened Finish: Premium Salt Bath Nitride finish shields internal rifling and external steel surfaces to provide excellent friction reduction and all-weather corrosion defense.

Why Choose This Product?
Running a high-velocity 5.56 NATO round through a compact 10.5-inch barrel typically creates a punishing concussive signature. For a left-handed shooter on a standard right-hand upper, this means breathing in heavy exhaust gas while trying to ignore distracting muzzle flash. The PRO2A Left Hand Side Charging Flash Can Upper elegantly addresses every single one of these operational hurdles. By combining a dedicated left-ejecting chassis with a project-forward linear flash can, noise and hot debris are pushed completely away from your eyes and ears. Complete with a fluid, stationary side charging handle that allows fast manipulation without breaking your optic alignment, this assembly offers southpaw operators a smooth-cycling, compact powerhouse built to perform under pressure.
