Product Description

Maximize close-range maneuverability and straight-wall firepower with the premium PRO2A 7.5" 350 Legend Pistol Length Melonite M-LOK AR-15 Assembled Upper Receiver. Purpose-built as a standalone compact barreled upper assembly, this unit features a ultra-short 7.5-inch precision barrel engineered to satisfy heavy impact requirements from a highly portable footprint. This assembled upper receiver pairs a headspaced micro barrel with an adaptable 1:16 twist profile and a clean-cycling pistol-length direct impingement gas setup. Please Note: This is an assembled barreled upper receiver assembly only. It does not include a bolt carrier group (BCG), charging handle, lower parts kit (LPK), or rear stock hardware.

Key Features

• Barreled Upper Configuration Only: Fully assembled and headspaced mil-spec upper housing, precision micro barrel, low-profile gas block, gas tube, and free-float rail muzzle assembly. Excludes bolt groups, standalone charging handles, lower frame parts, or stock networks.
• Ultra-Compact Micro Footprint: A premium 7.5-inch heavy-duty barrel offers an exceptionally small maneuverability profile ideal for personal defense, truck builds, and tight-clearance hunting blinds.
• Straight-Wall Performance: Specifically optimized for the 350 Legend cartridge, granting heavy downrange energy transfer from a compact modern sporting platform configuration.
• Precision 1:16 Twist Rate: Perfectly tailored twist dynamic stabilizes standard and high-grain commercial ammunition options to maintain solid terminal ballistics.
• QPQ Melonite Hardened Protection: Inside barrel bore, chamber throat, and exterior walls are fully liquid nitrocarburized to maximize surface hardness, improve thermal dissipation boundaries, and resist extreme environmental degradation.
• Modular Free-Float Workspace: A continuous top Picatinny rail aligns flawlessly with a slimline free-floating M-LOK handguard for secure accessory attachment without warping barrel zero.

Why Choose This Product?

The PRO2A 7.5" 350 Legend Pistol Length M-LOK Upper Receiver offers custom builders an exceptional, micro-sized baseline without forcing the purchase of redundant bolt carrier elements or lower parts you may already have on hand. Sourcing standalone components for unique calibers often creates headspacing risks or feeding failures with straight-walled cases. This system resolves that constraint out of the box, utilizing a single large M4 feed ramp configuration built explicitly to chamber straight-wall ammunition smoothly. Complemented by a free-floating rail that provides ample space for custom hand placement or tactical attachments, it delivers a flat-shooting, modern profile engineered for extreme operational environments. Built in America to exacting manufacturing tolerances and guarded by an unconditional Structural Lifetime Warranty, it stands out as a highly reliable choice for your next compact firearm configuration build expansion.
