Living on the Florida coast means dealing with heat, humidity, and salt air every single day. Your EDC gear has to hold up to that environment, and your optic mount is no exception. The Super Clamp for Steiner MPS is a direct replacement for the factory clamp that came with your optic. It is machined from solid steel and finished with a black oxide treatment, giving you a corrosion-resistant surface that stands up to sweat, sea spray, and the constant moisture of coastal life. At just $20, this is a simple upgrade that solves a real problem for anyone running a Steiner MPS on a handgun or carbine.

The core benefit here is compatibility. The factory clamp on your Steiner MPS is designed to fit only the specific dovetail on Steiner’s own mounts. That limits your options. The Super Clamp expands the clamping range so your MPS can attach to any optic mount cut within the standard ACRO mounting specs set by Aimpoint. This means you can use your Steiner on popular ACRO-compatible slides, adapter plates, and aftermarket mounts without any modification. You are not locked into one ecosystem anymore.

• Replaces the factory optic clamp — direct swap, no special tools required. Just remove the original clamp, install the Super Clamp, and you are good to go.
• Expands mounting compatibility — works with all optic mounts that are machined to the standard ACRO tolerances as provided by Aimpoint. This includes most modern handgun slides cut for ACRO footprint, as well as aftermarket adapter plates.
• Steel construction with black oxide finish — the steel body provides a secure, rigid lockup, while the black oxide coating adds a layer of corrosion resistance that is essential for Florida carry. No rust spots from daily sweat or beach trips.
• Cost-effective upgrade — for $20, you avoid the hassle of buying a new optic or replacing a perfectly good mount. It is a practical fix, not a luxury add-on.

Torque Specs: Steiner recommends the fastening screw be torqued between 15 and 20 in-lb (inch-pounds) for proper installation. Use a quality torque driver to avoid over-tightening. This ensures the clamp holds securely without damaging the optic body or the mount.

Fitment and compatibility notes: This clamp is specifically designed for the Steiner MPS optic. It does not fit other optics or non-ACRO mounts. If you are running a slide or mount that is cut specifically for the ACRO footprint (including the Aimpoint ACRO P-1, P-2, and similar), the Super Clamp will allow your Steiner M
