Frequently Asked Questions
Will the Fulcrum-45 fit any AR-15 or AR-10 lower receiver?
The Armaspec Fulcrum-45 is compatible with standard mil-spec AR-15 and AR-10 lower receivers, but it specifically requires that your lower receiver have 45-degree FIRE markings. Because the selector stops at 45 degrees rather than the traditional 90 degrees, using it on a lower marked only for 90-degree selectors will result in a misalignment between the selector position and the receiver's FIRE marking. Always verify your lower's markings before installing this selector.
Is the Fulcrum-45 a drop-in installation, or does it require gunsmithing?
The Fulcrum-45 is designed as a straightforward drop-in replacement for your existing safety selector. Most shooters comfortable with basic AR-15 lower parts installations can complete the swap with standard armorers' tools. No permanent modifications to the receiver are required. If you are unfamiliar with AR-15 lower parts work, a qualified gunsmith can install it quickly and inexpensively.
How does a 45-degree safety selector improve performance over a standard 90-degree selector?
A 45-degree safety selector reduces the arc your thumb must travel to move from SAFE to FIRE by half compared to a traditional 90-degree selector. This shorter throw allows for faster disengagement, reduces wrist strain during rapid transitions, and keeps your firing grip more consistent throughout the motion — advantages that matter most in competitive shooting, dynamic drills, and defensive situations where speed and control are critical.
