Tapco's TAP22037 kit includes the essential fire control and retention components required to complete an AR-15 lower receiver assembly. The kit is manufactured to mil-spec dimensions, ensuring compatibility with standard lower receivers and upper assemblies across the AR platform ecosystem. Each component is finished to resist corrosion in field conditions, and the assembly design follows proven mechanical principles that have proven effective across law enforcement and military applications for decades. The compact 3 x 1.6 x 4.9-inch packaging contains precisely the parts needed without excess bulk or unnecessary materials.

This lower parts kit serves armorers, range operators, tactical trainers, and individual builders seeking to maintain weapon systems or assemble dedicated training rifles. Installation requires basic mechanical knowledge and standard gunsmithing tools; the components integrate directly into mil-spec AR-15 lower receivers without modification. Tapco's reputation for producing field-proven components makes this kit particularly valuable for organizations managing rifle inventory where consistency and interchangeability across multiple platforms is critical for operational efficiency and maintenance protocols.
