Del-Ton M4 Rifle Kit 16" Barrel

The Del-Ton M4 Rifle Kit 16" Barrel is a complete upper receiver assembly engineered for shooters who demand a proven, field-tested foundation for 5.56 NATO builds. This 16-inch M4 profile barrel kit combines practical carbine ergonomics with components specified to military standards, delivering a reliable platform for patrol, training, and general-purpose rifle use.

The barrel features chrome moly vanadium construction with M4 feed ramps, a 1x9 twist rate, and M4-profile geometry—the same profile used across military and law enforcement carbines worldwide. The manganese phosphate finish resists corrosion during extended field operations, while the threaded muzzle accepts standard aftermarket flash hiders or suppressors. The F-marked front sight base incorporates taper pins and is phosphated under the base for durability. At 7.02 lbs, the complete kit remains maneuverable in close-quarters scenarios while maintaining enough mass for recoil control and heat dissipation during sustained fire.

This kit suits law enforcement training programs, military-specification builds, and civilian shooters seeking components with established duty-grade reliability. The 16-inch barrel length is optimal for indoor ranges and vehicle-based operations where 20-inch rifle configurations prove unwieldy. Operators and serious enthusiasts who prioritize parts traceability and standardized military dimensions will find this kit compatible with mil-spec lower receivers and common modular handguards.

Del-Ton barrels are known in the tactical community for holding service-grade accuracy and longevity when maintained properly. The 5.56×45mm chamber chambers both standard 5.56 NATO and civilian .223 Remington ammunition, giving shooters flexibility at the range. Whether building a designated marksman rifle, a patrol carbine, or a training platform, this M4 rifle kit offers the specifications and materials expected by professional end users.
