AR10/AR15 Pivot & Takedown Pin Springs, Ten-Pack Spares
Pivot and takedown pin springs are small components with an outsized role: they apply tension that keeps the detents seated and your upper and lower receivers held tight during use. This ten-pack gives builders and gunsmiths spares on hand for new AR-15 and AR-10 assemblies, replacement during maintenance, or recovery of springs lost during disassembly. Proudly Made in the USA.
Because detent and spring dimensions can vary between manufacturers, confirm fitment against your specific lower receiver and pin hardware before installation. Handle these small springs carefully to avoid loss. Pair them with the magazine catch spring ten-pack and a safety selector and ejector spring set to stock a complete small-parts bin.
Keeping extras on hand helps avoid downtime mid-build. Builders rounding out a lower can also add the bolt catch detent spring ten-pack to cover routine maintenance needs.
