Armaspec Fulcrum 45/90 Ambidextrous Safety Selector – AR-15/AR-10

The Armaspec Fulcrum 45/90 is an ambidextrous safety selector designed for AR-15 and AR-10 pattern rifles. It offers shooters the choice between a traditional 90-degree throw or a shorter 45-degree rotation, allowing for faster manipulation without sacrificing positive engagement. The ambidextrous design accommodates both left- and right-handed shooters and provides tactile feedback at both safe and fire positions.

Machined from steel with a black finish, the Fulcrum features a low-profile lever on the off-side to minimize snag points while maintaining full ambi functionality. Installation is straightforward and requires only standard AR lower receiver tools—no permanent modifications to the receiver are needed. The selector includes all necessary components for installation.
