One Horse AR-15 Spare Parts Kit

Keep the tiny parts that love to fly across the room on hand before they disappear under the workbench. The One Horse AR-15 Spare Parts Kit packs every small spring, detent, and pin that commonly goes missing during AR-15 builds and maintenance into one inexpensive backup package.

The One Horse AR-15 Spare Parts Kit is a collection of commonly lost AR-15 small parts designed for emergency replacement during builds, maintenance, and range sessions.

You get the springs, detents, and pins that are most likely to launch during installation or break during use, giving you instant access to replacements without stopping your build or range day. Keep the kit in your range bag, toolbox, or parts bin so a missing detent or broken spring is a quick fix instead of a project-ending problem.
