Product Overview
The PRO2A 10.5" .45 ACP 1/16 Pistol Caliber NR Side Charging Melonite M-LOK Upper Kit provides a comprehensive, high-performance conversion package engineered to deliver heavy-hitting pistol caliber dominance within the modular AR footprint. Centered around a premium 10.5-inch 4150 CMV steel barrel with a rugged Melonite finish, this complete system extracts optimal velocity and accuracy from the iconic, hard-hitting .45 ACP cartridge. Featuring an elite Non-Reciprocating (NR) side-charging handle for rapid manual manipulation beneath optics, this comprehensive kit drops seamlessly onto your choices of Glock-compatible or dedicated .45 ACP mil-spec lower assemblies.
Key Features
Non-Reciprocating Side Charging Billet Receiver: Manual side charging mechanism remains entirely static during live fire sequences, clearing crucial workspace and preventing optical rail interference.
Precision 1/16 Twist Rate: Precision-button rifling delivers uniform projectile stabilization dialed in specifically for heavy-grain standard and subsonic .45 ACP defensive loads.
Independent Free-Float M-LOK Handguard: Isolates target barrel harmonics from accessory weight while offering an expansive top Picatinny rail and modular M-LOK mounting real estate.
All-In-One Conversion Bundle: Ships fully bundled with a specialized side-charging Bolt Carrier Group (BCG), an ergonomic slim handguard, a full lower parts kit matrix, and pistol buffer tube hardware gear.
