Super Clamp for Steiner MPS Optic

If you run a Steiner MPS on your pistol or carbine, you already know the factory clamp is limited. It only works with mounts cut specifically for the MPS. That means you are stuck, or you are swapping out entire mounting plates just to fit different slides or adapter systems. The Apex Super Clamp fixes that problem for twenty bucks. It replaces the original optic clamp that came with your Steiner MPS and lets you mount that optic onto any dovetail mount or adapter that follows the ACRO footprint specs set by Aimpoint. No more hunting for rare MPS-specific plates. No more filing down mounts to make things fit.

This clamp is machined from steel and finished with a black oxide coating. It is not a soft aluminum part that will strip or deform under recoil. The steel construction gives you a solid, repeatable lock-up on the optic rail, and the black oxide finish resists corrosion without adding glare. The expanded clamping range is the real benefit here: you can take an MPS that was previously limited to one type of mount and put it on any optic mount that follows the ACRO standard tolerances. That includes popular mounts from companies like Forward Controls Design, CHPWS, and many aftermarket slide milling options. If the mount says it works with an ACRO, this clamp will make your MPS work with it.

• Replaces the factory MPS clamp – Direct swap, no modifications to the optic itself.
• Expands mounting compatibility – Works on all dovetail mounts and plates cut to ACRO standard tolerances (Aimpoint ACRO footprint).
• Steel construction – Machined from steel, not cast or sintered. Black oxide finished.
• Torque spec – Steiner recommends 15 to 20 in-lb on the fastening screw. Use a quality torque driver for consistent results.

This is a no-nonsense part for shooters who want one optic that fits multiple hosts without buying a new optic for each platform. If you bulk-buy mounts for different pistols, or if you swap optics between a handgun slide and a carbine adapter, this clamp saves you money and hassle. At twenty dollars, it is cheaper than buying a second MPS or tracking down rare adapter plates. It also makes your inventory easier to manage: one optic, one footprint, one clamp.

Fitment note: This clamp is specifically for the Steiner MPS. It will not work on other optics. The ACRO footprint compatibility means the mount or plate you use must be cut to the standard ACRO dimensions (same as Aimpoint ACRO P-1, P-2, and
