Tacfire AR-15 Buffer Detent Pin with Spring USA Made

The Tacfire AR-15 Buffer Detent Pin with Spring is an essential component designed for AR-15 and AR-10 platforms. This small yet critical part secures the buffer tube assembly to the receiver, preventing accidental separation during operation or maintenance. Ideal for shooters, military personnel, law enforcement, and gunsmiths, it ensures reliable firearm function.

Manufactured to OEM specifications, the Tacfire buffer detent pin features a precision-engineered spring mechanism that provides consistent engagement without over-compression or binding. The spring maintains proper tension to keep the pin seated in the lower receiver while allowing smooth installation and removal during maintenance cycles. USA manufacturing guarantees dimensional consistency and material quality that meets or exceeds mil-spec tolerances.

This component is compatible with standard AR-pattern receivers and works seamlessly with mil-spec and commercial buffer tube assemblies. Installation requires no specialized tools—simply insert the detent pin and spring into the designated hole on the lower receiver before attaching the buffer tube. Armorers and gunsmiths will appreciate the ease of use and reliability this product offers.
