The Armaspec FULCRUM-45 is an ambidextrous 45° safety selector for AR-15/AR-10 platforms. It is designed to engage around the 45° point instead of the standard 90°, allowing faster disengagement. Smooth, easy-to-reach levers make position selection fluid, while a crisp lockup ensures confidence in safety status. Once installed, it operates intuitively from either side of the receiver.
⚠️ Important: Use only on lowers that have the correct 45° FIRE markings. Do not use on receivers without these markings; in that case, the 90° side should be used.
