One Horse OH-OS01 AR-15 Spare Springs, Detents & Pins Kit

The One Horse OH-OS01 AR-15 OH-SHYT Kit is a compact spare parts kit built for AR-15 builders and armorers who want the small but essential hardware kept on hand. The kit pulls together the most commonly lost or worn small components - springs, detents, and pins - into a single convenient package so you can rebuild, repair, or complete a lower receiver without chasing down individual pieces.

Every part is finished in black to match standard AR-15 hardware, and the kit is multi-caliber compatible, making it a useful addition to any AR-15 workbench, parts bin, or range bag. It is manufactured in the USA by One Horse LLC as part of their growing line of rifle components focused on practical, no-nonsense parts.

Whether you are finishing a fresh build, replacing hardware that walked off the bench, or just keeping a complete spare set on hand for the next range session, the OH-OS01 delivers the exact small parts an AR-15 lower relies on in one tidy, ready-to-use kit.
