PRO2A LEFT HAND 22" 6.5 Grendel 1/8 Rifle Length Melonite M-LOK AR-15 Upper Kit

Product Description

Squeeze the absolute maximum velocity, absolute distance thresholds, and flat tracking capabilities out of the 6.5 Grendel cartridge. The PRO2A LEFT HAND 22" 6.5 Grendel Upper Kit is engineered from the ground up to deliver a true match-grade long-range precision platform for southpaw operators. Utilizing a mirrored left-ejecting receiver profile and a matching left-hand M16 bolt carrier group, this complete rifle package routes gas blowback and spent casings safely down the left side, keeping your line of sight clear. The maximum-length 22-inch medium profile barrel ensures complete powder burn efficiency, yielding optimal downrange kinetic retention. Combined with an all-inclusive lower receiver build group and stock assembly, this kit provides everything required to finish your custom southpaw precision rifle build.

Key Features

True Left-Hand Architecture: Mirrored left-side ejection keeps spent casings, visual distractions, and mechanical gases far away from southpaw shooters.
Extended 22-Inch Velocity: Extracts maximum terminal ballistics and optimal kinetic energy parameters from the 6.5 Grendel round, serving as the ultimate long-range hunting and precision target platform.
Ultra-Smooth Rifle Gas System: Elongated gas transit drops dwell times and cyclic port pressures, generating a soft, highly controllable shooting experience.
Premium QPQ Melonite Finish: Liquid nitride hardened 4150 Chrome Moly Vanadium barrel ensures severe weatherproofing, extreme throat life, and prolonged precision.
Complete Rifle Build Setup: Features a complete lower parts kit and a standard adjustable rifle stock assembly—no piecemeal component sourcing required.
