Del-Ton AR-15 16" DTI M4 CL 1x7 Barrel Assembly 16" Barrel Black with F Marked Front Sight Base

The Del-Ton AR-15 16" DTI M4 CL 1x7 Barrel Assembly is a complete, drop-in upper receiver component engineered for law enforcement, military, and civilian tactical shooters who demand reliability without compromise. This barrel assembly combines a 16-inch chrome-moly steel barrel with an integral F-marked front sight base, eliminating the need for separate sight installation and reducing assembly complexity. Whether you're building a patrol rifle, home-defense platform, or precision trainer, this assembly delivers the modular flexibility that modern AR platforms are known for while maintaining the durability standards expected in professional environments.

Del-Ton's DTI M4 CL configuration features a 1-in-7-inch rifling twist rate, optimized for stabilizing a wide range of 5.56 NATO and .223 Remington loads from 55-grain varmint rounds through 77-grain match ammunition. The F-marked front sight base is correctly dimensioned per military specification, ensuring co-witness alignment with standard AR-height optics and providing a proven backup aiming solution. The barrel assembly's 5.41-pound weight and compact 16-inch length make it ideal for close-quarters tactical work, vehicle-based operations, and confined-space environments where maneuverability and target acquisition speed are critical. Chrome-moly construction provides superior corrosion resistance and heat dissipation compared to standard steel, extending service life in demanding field conditions.

This barrel assembly integrates seamlessly with any AR-15 upper receiver featuring standard .750-inch diameter gas tube mounting and is compatible with both mil-spec and commercial buffer systems. Installation requires proper torque-wrench procedures and headspace verification—essential steps that cannot be overlooked in professional applications. Law enforcement armorer courses and military maintenance protocols recognize the importance of precise assembly, and the DTI M4 CL's straightforward design facilitates rapid maintenance cycles. Shooters upgrading existing uppers or building complete rifles will appreciate the time savings and indexing accuracy that a factory-assembled barrel system provides, along with Del-Ton's reputation for consistent quality and documented test performance.
