The Talon ambidextrous safety selector is a modular design that can be installed as a standard 90 or as a 45 short throw by simply rotating the shaft 180 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. Made in the USA. | Radians R0018 Talon 45/90 Ambi Safety
