Overview

Designed for the Rare Breed Triggers FRT-RD3, this Selector Detent Kit provides essential replacement parts for maintaining the safety selector system. Crafted from durable alloy steel and coated with black oxide, these components are built to withstand regular use. The kit is tailored for semi-automatic operation, ensuring one round is fired per trigger pull. Installation may require minor fitting to ensure proper function within the FRT-RD3 assembly. This kit is ideal for owners of roller-delayed HK pattern firearms or those maintaining AR or AK platforms. It addresses wear or damage to the selector detent, ensuring reliable engagement of the safety mechanism. Priced at $11.00, this kit ships direct from MP5 FRT, a trusted source for HK, B&T, AR-15, and AK parts.
