Del-Ton AR-15 Complete Lower Parts Kit - St. Trigger

The Del-Ton AR-15 Complete Lower Parts Kit - St. Trigger is the foundational component set every AR-15 builder or armorer needs to complete a lower receiver assembly. Whether you're constructing your first rifle, upgrading an existing platform, or maintaining inventory for a tactical unit, this kit eliminates the frustration of sourcing individual components from multiple suppliers. Del-Ton has earned respect in professional and civilian markets for delivering mil-spec compatible parts at competitive pricing, making this lower parts kit a reliable choice for consistency and interchangeability.

This complete kit includes all necessary lower receiver components, with a straight trigger as the centerpiece—a proven upgrade over standard mil-spec designs. The straight trigger geometry reduces perceived takeup and provides a more direct trigger wall, benefiting shooters who prioritize speed and reset feedback during rapid fire or precision work. All included components are manufactured to USGI dimensions, ensuring drop-in compatibility with standard AR-15 lower receivers without modification. The kit's compact 5 x 1.4 x 9.5-inch footprint and 0.6-pound weight make it ideal for shipping, storage, or transport to the range or armory.

Law enforcement armorers, military personnel, and competitive shooters benefit most from stocking this kit for quick rifle builds or repairs. Installation is straightforward for anyone with basic mechanical aptitude and a proper lower parts kit assembly tool—no gunsmith required. The kit's mil-spec compliance ensures compatibility across all standard AR-15 lower receivers, from basic utility rifles to precision builds. Experienced builders appreciate Del-Ton's quality control and the time savings of purchasing all parts together rather than individual sourcing.
