Upgrade your AR-40 build with this high-performance .40 S&W 16" Slick Side Lightweight Upper Assembly, engineered for precision, durability, and reliability. Featuring a blowback gas system and a hexagon blast can for superior recoil control, this upper ensures smooth operation and optimal performance. This upper is Non-LRBHO.
Built with a 4150 chrome-moly steel barrel, melonite-coated for enhanced wear resistance, this 16.1" threaded barrel (0.578x28) with a 1:16 twist is designed for accuracy and longevity. The slick side billet aluminum upper receiver eliminates unnecessary bulk, offering a streamlined, lightweight design without a forward assist or dust cover.
The 15" free-floating Mlok handguard provides superior heat dissipation and a secure, ergonomic grip, making it ideal for tactical setups or competitive shooting. Included in this package is a precision-milled, M-16 cut AR-40 ramped BCG, designed for use with both Glock-style and traditional AR-9 lower receivers. A standard AR-15 charging handle is also included for convenience.
