AR10/AR15 Bolt Catch Detent Spring Ten-Pack for Builds and Repairs
The bolt catch detent spring applies the tension that keeps the bolt catch engaging positively and staying secure during operation and reloads. As a small part of the AR fire control and receiver hardware, a worn or lost detent spring can affect how the bolt catch holds, which makes keeping spares on hand worthwhile. This ten-pack gives builders and gunsmiths a working supply for new builds, repairs, and replacements, and it is made in the USA.
Detent springs are easy to misplace during assembly, so extras help avoid downtime mid-build. Builders rounding out a receiver parts kit often pair this with the magazine catch spring ten-pack and the pivot and takedown pin spring.
For fire control work, the disconnect spring ten-pack is a useful companion. Verify compatibility with your AR-15 or AR-10 components before installation.
