The Armaspec Fulcrum-45 is an ambidextrous safety selector for AR-15 and AR-10 lowers. It moves to fire at about 45 degrees instead of 90, so the safety comes off faster, and it locks up crisply in each position. Levers on both sides suit either hand. Use the 45-degree side only on receivers with 45-degree fire markings; otherwise use the 90-degree side.
