Enhanced Aesthetics and Performance

This 300BLK M4E1 comes with many enhanced features. Key features include quick disconnect sling sockets and an enhanced milling design that provides a surer grip and improved visual appeal. The handguard mounting platform is forged into the upper receiver, making this complete upper a much more robust system.

High-Quality Craftsmanship

The low-profile gas block and new profile Picatinny top scalloped rails make it easy for the shooter to carry and handle while making for faster and more precise target acquisition. The barrel is cut from 4150 chrome moly vanadium for strength and is coated with a QPQ corrosion-resistant finish for added durability and attractiveness. The M4 feed ramp extension makes for smooth ammo cycling, and the A2 flash hider helps stay on target by increasing sight picture retention.
