Radical Uppr 300blk 16" 1-8 Mlok Blk

The Radical Uppr 300blk 16" 1-8 Mlok Blk is a modern rifle upper receiver assembly built on the proven .300 Blackout platform. The 16-inch barrel length strikes a practical balance between velocity and portability, making this upper receiver suitable for intermediate-range precision work, home defense configurations, and training applications where compact maneuverability matters. The 1-in-8 twist rate stabilizes a wide range of .300 Blackout projectiles, from lightweight 110-grain rounds to heavier 220-grain subsonic loads, providing flexibility across ammunition types without sacrifice in accuracy.

The M-LOK mounting interface along the handguard delivers industry-standard accessory compatibility, allowing operators to attach tactical lights, vertical grips, sling points, and optic mounts without rail real estate limitations. The 16-inch configuration reduces overall sight radius compared to longer barrels while maintaining the ballistic efficiency the .300 Blackout cartridge demands in suppressed and unsuppressed duty. Black Cerakote finish provides corrosion resistance and a professional mil-spec appearance. This upper receiver is engineered to function reliably when paired with appropriate lower receivers and ammunition specifications.

This configuration serves shooters who want a dedicated .300 Blackout upper receiver for existing AR-pattern lower receivers, whether for precision rifle courses, duty weapon builds, or modular firearm systems. The 1-in-8 twist supports both subsonic and supersonic ammunition, eliminating the need for dedicated uppers when switching ammunition types. Operators familiar with AR ergonomics will find the M-LOK platform immediately accessible, and the 16-inch length suits shooters prioritizing compact profiles without sacrificing barrel capability. Whether configured for suppressed operation or conventional shooting, this upper delivers the modern .300 Blackout performance that serious shooters expect.
