Overview

The FRT-RD3 SEF Selector Kit is engineered specifically for PTR MP5 clones, enabling seamless compatibility with Rare Breed Triggers' FRT-RD3. Crafted from heat-treated 4140 steel and anodized 7075 aluminum, this kit ensures durability and precise function in roller-delayed firearms. It replaces the factory safety selector and maintains the SEF grip frame layout without requiring modifications to the host firearm. Proper fitting may be necessary during installation to ensure optimal performance. This semi-automatic component fires one round per pull of the trigger and ships directly without FFL requirements. Ideal for enthusiasts seeking to enhance their PTR MP5 clone’s functionality, this kit is a reliable upgrade for those familiar with HK pattern guns or exploring similar options for AR or AK platforms.
