Product Description

The PRO2A Left Hand 11.5" 5.56 NATO Carbine Length Melonite M-LOK AR-15 Upper Kit is an all-inclusive conversion package precision-engineered for left-handed operators building a high-reliability short-barreled rifle or pistol platform. This complete build kit removes all component 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 assembly, providing southpaw builders with everything required to turn a standard stripped lower receiver into a highly maneuverable platform with superior dwell time.

Key Features

• True Left-Hand Configuration: Mirrored left-side ejection port orientation redirects hot gas blowback and spent shell casings completely clear of a southpaw shooter's face and eyes.
• 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.
• Reliable Carbine-Length System: Features an optimized gas port layout that ensures reliable dwell time and cycling stability across a broad array of standard 5.56 NATO loads.
• Premium Melonite Structural Defense: Heavy-duty 4150 CMV steel barrel is liquid nitrided to secure exceptional corrosion protection, easier cleaning, and an extended throat longevity profile.

This streamlined package ensures uniform cycling reliability, presenting an exceptional foundation for close-quarters platforms or home-defense configurations.
