The Armaspec Fulcrum-45 is an ambidextrous safety selector for AR-15 and AR-10 lowers. It moves to fire at roughly 45 degrees instead of the standard 90, which makes disengaging the safety faster, while still locking up crisply in each position. Levers on both sides let left- and right-handed shooters run it naturally. Use the 45-degree side only on receivers marked for a 45-degree fire position; otherwise use the 90-degree side.
