Apex Optic Mount for FNX-45 – ACRO/MPS* Optics

Description

This Apex Optic Mount provides a secure, steel mounting solution for your FNX-45 Tactical, built specifically for shooters who need their gear to hold zero under hard use. Machined from solid billet steel with a black oxide finish, this mount offers durability that outlasts aluminum alternatives, ensuring your optic stays locked in through thousands of rounds at the range or in concealed carry training.

Designed exclusively for FNX-45 Tactical models with the factory optic cut, this mount installs directly onto your factory slide using the included screws with thread locker pre-applied. No modifications, no gunsmith fitting—just a direct swap that gets your optic on the gun fast. The mount accepts the following optics:

• Aimpoint ACRO P-1 & P-2
• Steiner MPS
• Lead & Steel Pandora PB-3

Important fitment note for MPS users: The Steiner MPS requires the Apex Super Clamp to expand the clamping range of the optic. We strongly recommend pairing this mount with the Super Clamp if you’re running an MPS to ensure a proper, repeatable zero.

Mounting screws included – This mount ships with a set of optic plate mounting screws that have thread locker pre-applied. If you misplace these screws, you can substitute the short 5-40 threaded screws that came with your FNX-45 Tactical from the factory. This gives you a reliable backup option without hunting for specialty hardware.

Real-world benefits for practical shooters and hunters: The steel construction adds negligible weight to your slide but provides the rigidity needed for consistent impact shift when using a red dot. For concealed carry, this mount keeps your optic low-profile and snag-free, while the black oxide finish resists holster wear and corrosion from sweat or weather. Hunting with an FNX-45? The direct mount design eliminates the need for adapter plates that can loosen over time, giving you one less point of failure in the field.
