Product Description

The PRO2A Left Hand 18" 223 Wylde Mid Length Stainless Premium M-LOK AR-15 Upper Kit is an all-inclusive conversion package precision-engineered for left-handed shooters looking to build a highly accurate, match-grade tactical or marksman rifle assembly. Chambered in the versatile 223 Wylde bore to maximize accuracy thresholds for both 5.56 NATO and .223 Remington ammunition, this comprehensive bundle eliminates all parts-matching guesswork. It pairs a true left-ejecting forged upper receiver and specialized left-handed bolt carrier group with a premium 416R stainless steel barrel, a full lower completion hardware pack, and an adjustable stock system, transforming any standard stripped lower receiver into a premier southpaw field rifle.

Key Features

• True Left-Hand Configuration: Mirrored left-side ejection port orientation safely directs scorching expansion gases and hot empty shell casings completely clear of a southpaw shooter's face and eyes.
• Match-Grade Stainless Barrel: Crafted from premium 416R stainless steel to deliver superior concentricity, enhanced bullet consistency, and extreme target precision at extended ranges.
• Hybrid 223 Wylde Chambering: Specially engineered chamber geometry accommodates the higher pressures of 5.56 NATO loads while maintaining the precise accuracy dimensions needed for match .223 Remington cartridges.
• Smoother Mid-Length Gas Profile: Employs an intermediate gas port distance to drop cyclic pressures and bolt slide speed, resulting in significantly smoothed out recoil metrics and lower internal parts fatigue.
• All-In-One Rifle Completion: Bundles your high-accuracy 18-inch stainless upper assembly with a dedicated left-hand BCG, standard top-charging handle, complete lower parts kit, and an adjustable stock completion package.
