Del-Ton AR-15 Upper Receiver Parts Kit

The Del-Ton AR-15 Upper Receiver Parts Kit is a precision component assembly designed for the field assembly and maintenance of direct impingement AR-15 platform rifles. This kit provides the essential internal hardware for the upper receiver's ejection port and forward assist mechanism, making it indispensable for armorers, builders, and operators performing upper receiver assembly or component-level repair in the field.

The kit includes all critical ejection port components—cover, pin, spring, and hinge pin clip—plus forward assist subassembly hardware: forward assist round, pin, and spring. These are standardized mil-spec or commercial-spec parts that are fully compatible with mil-spec upper receivers. The forward assist mechanism allows controlled chambering of a cartridge when the bolt carrier fails to fully seat under its own inertia, a critical function during adverse conditions or with certain ammunition lots. The ejection port cover protects the receiver interior from environmental contamination during storage or transport while remaining easily accessible for rapid deployment.

This kit is essential for rifle builders sourcing individual components, armorer technicians conducting repair work, or operators who prefer to maintain replacement parts on hand. Del-Ton's parts kits are manufactured to mil-spec dimensions and tolerances, ensuring zero compatibility issues with standard upper receivers. The lightweight construction (0.16 lbs) makes this a logical addition to an armorer's kit bag or range box when supporting multiple rifles.

Whether performing a complete upper receiver assembly, replacing worn ejection port hardware, or maintaining a spare parts inventory, the Del-Ton AR-15 Upper Receiver Parts Kit delivers verified mil-spec compatibility without the need to source individual components separately. SKU DGUP1050 ensures consistent ordering and inventory management for dealers and end-users alike.
