Frequently Asked Questions

Which sights is the Aimpoint 200666 compatible with?

The manufacturer specifies the mount for sights with the Aimpoint ACRO interface. Before purchasing, check the exact model of your sight and its mounting interface, as Aimpoint Micro and other interfaces are not the same as ACRO.

What does 22 mm mean for this mount?

This indicates the optical axis height of the sight when using the mount. It does not refer to the Picatinny rail width or the overall height of the mount.

Is the mount compatible with both Picatinny and Weaver rails?

Yes. Aimpoint states the product is suitable for both rail standards. However, always check the rail dimensions and condition on your specific firearm before installation.

Is this a quick-detach mount?

No. Product code 200666 refers to a fixed mount. The quickly removable ACRO QD Mount 22 mm is a different model with product code 200517.

Will the sight retain zero after removing the mount?

A fixed mount is not designed for frequent removal. After detaching, relocating, or reinstalling the mount, the point of impact should be checked at the range.

Is the 22 mm mount suitable for AR-type rifles?

Mechanically, it may fit a Picatinny rail, but a 22 mm optical axis height is very low for many AR-type rifles. Before purchasing, assess the stock height, cheek weld, and your desired sight picture.

Is model 200666 still in production?

The Aimpoint international website lists the model as discontinued and available while stocks last. This does not affect usability, but future availability of an identical new mount may be limited.

When is the Aimpoint ACRO Fixed Mount 22 mm the right choice?

This mount is suitable for firearms where the Weaver or Picatinny rail sits low enough and where you want to keep the ACRO sight as close to the barrel as possible. A low sight can provide a more natural head position on traditional stocks with a low cheek piece.

On AR-type rifles with a straight stock line, a 22 mm optical axis may be too low for comfortable aiming. In such cases, a higher ACRO mount is recommended. If you need to remove the sight frequently, the QD version with product code 200517 is more practical.

Recommendation

We recommend evaluating the entire combination of firearm and sight heights before purchasing, not just the rail standard. The 22 mm mount is low and works best with firearms whose stock allows your eye to naturally align with the sight axis. Too low a position will force you to tilt your head, making quick aiming uncomfortable.

Mount the base on a clean, undamaged rail. Insert the crossbolt fully into the rail groove and tighten the mount according to Aimpoint’s instructions. Excessive torque may damage the screw, mount, or firearm rail. After installing the ACRO sight, ensure all contact surfaces are flush and the sight does not move. Confirm the final point of impact at the range and recheck after removing or relocating the mount.

Low-profile original mount for Aimpoint ACRO sight

The Aimpoint ACRO Fixed Mount 22 mm combines the ACRO interface with a Weaver or Picatinny rail into a compact, fixed unit. It is an ideal solution for users who want a low sight position and do not require a quick-release mount.
