CMMG AR15 Receiver Detent 10-Pack – AR-15/M16 Platform

The CMMG AR15 Receiver Detent 10-Pack provides essential spring-loaded detents used to secure the takedown and pivot pins in AR-15 and M16 pattern rifles. These small but critical components hold pins in the closed position under spring tension, ensuring reliable operation of the upper and lower receiver connection. This 10-pack is ideal for armorers, builders, or shooters maintaining multiple rifles—detents are commonly lost during disassembly or wear over time.

Manufactured from heat-treated steel with a durable finish, these detents are direct replacements for factory parts. Installation requires disassembly of the lower receiver and careful compression of the detent spring—a punch and hammer are recommended. Consider having extras on hand; these are among the most frequently misplaced parts during AR builds and maintenance.
