From the manufacturer

Designed differently than traditional AR-15 safety selectors, the Armaspec ST45 cuts the traditional 90-degree throw in half, giving users short, fast travel from fire to safe and back again. The selector is ambidextrous, allowing users to quickly change the status of their rifle using either hand, and the throw is designed to be smooth and seamless when traveling in either direction. Each Armaspec ST45 safety selector is machined with aluminum levers sandwiching a steel core. The levers are locked into place with Torx screws, and the key needed for installation is included. The company warns that these levers should not be used on AR lower receivers that do not have "FIRE" Mfg: Armaspec
