Frequently Asked Questions

Does the cover need to match the diameter of the MAR clamp?

No. The MS-CLA is designed for the MAR system clamp side connection and is not selected based on the diameter of the sight lens housing.

Does it protect the clip-on device's MCR connector?

No. The MS-CLA is a protective cover for the clamp, i.e., the daytime sight side. A different type of cover is used for the device-side MCR connector.

Does the MAR clamp need to be removed to use the cover?

No. The cover is specifically designed for use when the clamp is left attached to the sight.

Does the cover replace the waterproof lens cover of the sight?

It provides practical protection against dirt and dust, but the weather resistance of the entire system depends on the adapter, optics, and the manufacturer's instructions.

When is the MS-CLA the right choice?

The MS-CLA is necessary when the MAR clamp is left attached to the lens of the daytime sight even when a thermal or night vision device is not in use. The cover allows you to protect the lens without removing the clamp.

Expert recommendation

Clean any loose dust from the lens and adapter before installing the cover. Make sure the cover is fully secured and remove any sand or other abrasive dirt from the inside of the cover that could damage the coating of the optics.
