Product Description

Optimize your custom configuration with the premium PRO2A LEFT HAND 22" 6.8 SPC II Rifle Length Melonite M-LOK AR-15 Assembled Upper Receiver. Built as a standalone barreled upper assembly, this unit features a 22-inch precision barrel paired with an optimized rifle-length direct impingement gas system to deliver a smooth cycling impulse and diminished port pressures. The architecture centers around a specialized left-handed forge configuration, providing unhindered left-side spent casing ejection and venting hazardous gases away from a southpaw shooter's face.

Key Features

• Dedicated Left-Hand Architecture: Specially cast left-handed forged aluminum receiver features a mirrored port setup to ensure completely reliable left-side ejection for natural southpaw operation.
• Maximized 22" Ballistic Profile: Extends the physical acceleration column to extract maximum muzzle velocity and optimal flat trajectories out of the specialized 6.8 SPC II hunting cartridge.
• Refined Rifle-Length Gas Dynamics: Softens the overall recoil impulse and dramatically slows component wear compared to over-gassed shorter setups by optimizing internal pressure dwell time.
• QPQ Melonite Hardened Protection: Inside barrel bore, chamber throat, and exterior walls are fully liquid nitrocarburized to maximize surface hardness, improve thermal dissipation, and resist extreme environmental degradation.
• Modular Free-Float Workspace: A continuous top Picatinny rail aligns flawlessly with a lightweight slimline M-LOK handguard for secure accessory attachment without warping barrel zero.

Why Choose This Product?

The PRO2A LEFT HAND 22" 6.8 SPC II Upper Receiver provides an exceptional, high-tier baseline configuration without forcing you to purchase redundant internal bolt assemblies or standard mil-spec lower components you may already own. Traditional right-charging or right-ejecting upper units create awkward physical manipulation clearances and blow noxious unburnt gas into your face when shooting from a left-hand mount. Utilizing Pro2A's specialized left-handed framework resolves this obstacle entirely, allowing clean operational execution while keeping your cheek weld firmly established. Built in America to exacting manufacturing tolerances and guarded by an unconditional Structural Lifetime Warranty, it stands out as a highly reliable choice for shooters demanding customized mechanical durability from an agile platform.
