Del-Ton 11.5" Pistol Kit

The Del-Ton 11.5" Pistol Kit represents a purpose-built upper receiver assembly designed for operators building short-barreled AR-platform firearms. This complete kit ships with a pre-assembled, headspaced, and test-fired upper receiver paired with all essential components needed to mate with a pistol-length lower receiver. The 11.5-inch barrel profile and carbine gas system balance velocity retention with compact handling characteristics suitable for close-quarters work, vehicle operations, and specialized tactical applications where standard rifle length introduces compromises in maneuverability.

The barrel features chrome moly vanadium construction with a 1-by-9 twist rate optimized for standard-weight 55- to 62-grain ammunition across common service calibers. The flat-top upper receiver incorporates white T-marks for rapid reference and M4-pattern feed ramps to ensure reliable ammunition feeding. The bolt carrier assembly undergoes HPT (high-pressure test) and MPI (magnetic particle inspection) quality verification, ensuring critical components meet military specifications for durability under sustained fire. Included carbine-length handguard provides mounting rails for accessories, while the pistol tube assembly with receiver end plate and castle nut simplifies integration with mil-spec buffer components.

This kit suits builders constructing short-barreled pistols, specialized patrol rifles, or training platforms where a proven, factory-tested upper assembly eliminates build-related quality variables. Law enforcement agencies, military personnel, and civilian operators familiar with AR-15 platform assembly will recognize the straightforward integration path. The pre-headspaced and test-fired upper reduces assembly complexity and ammunition waste during function verification, making this kit valuable for those prioritizing confirmed reliability over component sourcing and fitting.
