PRO2A LEFT HAND 7.5" 223/5.56 1/7 Pistol Length Melonite M-LOK AR-15 Upper Kit

Product Description

The PRO2A Left Hand 7.5" 223/5.56 Pistol Length Melonite M-LOK AR-15 Upper Kit is an all-inclusive conversion package precision-engineered for left-handed operators building a compact personal defense weapon or tactical pistol. This complete completion kit solves all parts-matching guesswork by pairing a true left-ejecting forged upper receiver and specialized left-handed bolt carrier group with a full lower completion parts kit and stock/buffer assembly. It provides southpaw builders with everything needed to convert a standard stripped lower receiver into a highly maneuverable close-quarters platform.

Key Features

True Left-Hand Configuration: Mirrored left-side ejection port orientation safely directs hot gas blowback and spent shell casings completely clear of a southpaw shooter's face.
Complete Build Integration: Bundles your high-accuracy short upper assembly with a dedicated left-handed BCG, standard charging handle, complete small lower parts, and an adjustable stock completion system.
Versatile Dual-Caliber Chambering: Precision engineered to reliably feed and fire both 5.56 NATO and .223 Remington cartridges without sacrificing gas system integrity.
Premium Melonite Structural Defense: Heavy-duty 4150 CMV steel barrel is liquid nitrided to secure exceptional corrosion protection, easier maintenance, and an extended throat life.
