Super Clamp for Steiner MPS Optic

Description

The Apex Super Clamp is a direct replacement for the factory clamp that comes with your Steiner MPS optic. Priced at $20, this is a straightforward upgrade designed to solve a specific fitment issue for California gun owners who run the Steiner MPS on non-standard mounts.

This steel clamp, finished with a black oxide coating, expands the clamping range of your MPS so it works on any dovetail mount cut to the ACRO mounting specs set by Aimpoint. That means if you have an aftermarket slide cut or a dedicated mount for an ACRO footprint, the Super Clamp ensures your Steiner MPS locks in securely without play or wobble. The factory clamp is limited in its adjustment range, which can cause problems when trying to mount an MPS on tighter or looser dovetails. The Super Clamp solves that by giving you a wider clamping envelope while maintaining the same overall dimensions and installation method.

Key benefits for your build:

• Steel construction: Machined from steel rather than softer materials, this clamp holds up to repeated torque cycles and keeps your zero consistent. The black oxide finish resists corrosion and blends in with the optic body.
• ACRO-compatible fitment: Works with all mounts, slides, and adapter plates cut to the standard ACRO footprint tolerances as provided by Aimpoint. No filing, shimming, or custom fitting required.
• Simple swap: Removes and replaces the factory clamp using the same screw and same installation steps. No new tools or modifications needed. You just swap the part and re-torque.
• Cost-effective fix: Instead of buying a new optic or a different mount, this $20 clamp lets you use your existing Steiner MPS on a wider range of platforms.

Torque specifications: Steiner recommends the fastening screw be torqued between 15 and 20 inch-pounds. Use a quality torque wrench or driver to avoid over-tightening, which can damage the clamp or the optic housing. Apply a small amount of blue Loctite to the screw threads before installation for added security.

Fitment notes: This clamp is specifically for the Steiner MPS optic. It will not fit other brands or models without modification. It is designed exclusively for dovetail mounts that follow the ACRO footprint standard. If your mount uses a different footprint (such as RMR, Docter, or Shield), this clamp will not work. Measure your mount’s dovetail width and depth against the ACRO standard before ordering to confirm compatibility.
