The Talon ambidextrous safety selector is a modular design that can be installed as a standard 90 degree or as a 45-degree short throw by simply rotating the shaft 180 degrees inside the lower receiver. Selector levers install using a precision machined dovetail interface with spring-loaded retention stud to lock the lever in place -no screws to come loose or break. The Talon is compatible with most semi-automatic AR15 & AR10/SR25-pattern rifles.
