PRO2A 5" 45 ACP 1/16 Pistol Caliber Melonite M-LOK Upper Kit - Suppressor Ready
Product Overview
The PRO2A 5" 45 ACP Suppressor Ready Master Upper Kit is engineered for maximum performance in an ultra-discreet, micro footprint. Purpose-built to be the ultimate host for your linear compensator or sound suppressor, this configuration matches a short 5-inch premium liquid-nitrocarburized barrel with a free-float handguard. This all-inclusive master build bundle comes populated with a dedicated blowback Bolt Carrier Group (BCG), standard AR-15 charging handle, complete Mil-Spec lower parts kit (LPK), and an adjustable receiver stabilizing brace assembly.
Key Features
- All-Inclusive Master Build Kit: Bundles the complete barreled upper receiver with a premium bolt carrier group, charging handle, full lower parts kit, and rear receiver pistol brace assembly.
- Ultra-Compact Profile: 5-inch heavy target barrel configuration delivers massive close-range kinetic energy transfer from a highly maneuverable, lightweight footprint.
- Suppressor-Ready Engineering: Designed with a tucked muzzle profile, allowing short suppressors or linear devices to thread safely inside the extended rail system for an integrated aesthetic.
- QPQ Melonite Extreme Armor: Barrel bore, chamber, and exterior are fully liquid nitrocarburized to exceed mil-spec chrome lining in surface hardness, heat dissipation, and corrosion resistance.
- Slim Profile M-LOK Workspace: Features a continuous top Picatinny rail interface seamlessly blended into a free-floating M-LOK handguard for rigid optics and accessory mounting stability.
