One Horse AR15 Complete Mil-Spec Lower Parts Kit

The One Horse AR15 Lower Parts Kit provides the internal components, controls and furniture needed to complete a compatible Mil-Spec AR15 lower receiver, with the exception of the buffer tube assembly and stock. It is intended for builders assembling a new lower or replacing a complete group of standard lower-receiver components with a coordinated kit. The included fire-control group uses a phosphate-coated, single-stage Mil-Spec trigger with a published pull range of 5.5 to 7 pounds. Its conventional geometry makes it a practical choice for a straightforward AR15 build where standard operation and broad Mil-Spec compatibility are priorities. Along with the trigger, hammer and disconnector assemblies, the kit supplies the selector and its detent hardware, bolt-catch components, magazine-catch components, pivot and takedown pins, associated detents and springs, and the buffer retainer with its spring. An A2-style pistol grip, grip screw, lock washer, trigger guard and trigger-guard roll pin are also included, helping reduce the number of separately sourced parts required to finish the lower. The components are precision-machined for installation in Mil-Spec AR15 lower receivers and are organized as a complete lower parts package rather than a reduced kit that omits the fire-control group. Because the receiver extension, buffer components and buttstock are not part of this package, builders can select those items separately to suit the intended rifle or pistol configuration while using this kit for the lower receiver’s operating controls and internal hardware. Manufactured in the United States, this One Horse kit is suited to a first build, a replacement project or a workbench supply where a comprehensive set of standard AR15 lower components is preferred. Installation should be performed with the correct tools and according to established AR15 assembly procedures.
