Product description

The CMMG Detent Pivot Spring AR-15 Silver is a detent spring designed for use with pivot and takedown pin assemblies in AR-15 receivers.

This CMMG Detent Pivot Spring AR-15 Silver is designed to fit standard AR-15 receiver configurations and provides tension for pivot and takedown pin detents. It functions as a small internal spring that maintains proper engagement of receiver pins during operation. This product is used for maintenance or replacement of spring components in rifle assemblies. In typical setups, the spring installs within the receiver channel and works with a detent to secure the pin. The silver finish defines its material appearance, and the compact design supports precise fitment. The CMMG Detent Pivot Spring AR-15 Silver fits AR-15 rifles with standard lower receiver specifications.
