The Rusan MAR modular adapter clamp is attached around the objective housing of an optical sight and is used to mount a thermal or night vision device in front of the scope. The quick-release lever and modular bayonet connection system allow the appropriate front device to be quickly installed and removed. Available in 57, 58, 62, 63, 64, and 65 mm variants. Suitable for use For mounting a thermal front device in front of an optical sight For attaching a digital night vision device For assembling the Rusan MAR modular system For quick installation and removal of various front devices For optical sights on hunting weapons For users who wish to leave the clamp attached to the scope Together with a corresponding Rusan MCR connection adapter for the device Why choose the Rusan MAR modular adapter clamp? Quick bayonet connection for thermal or night vision devices Quick-release lever for clamp installation Available in several precise diameters Allows removal of the front device without taking the clamp off the scope Precision-machined connection parts Robust aluminum construction Moving parts made of hardened steel Protective inner surface to maintain optical finish Fits Rusan MAR and MCR modular systems Compact design Made in Croatia Technical specifications Manufacturer: Rusan Mikron Product series: MAR Modular Adapter Product type: adapter clamp for attaching to the objective housing of an optical sight Purpose: connecting a thermal or night vision front device to an optical sight Device-side connection: Rusan MAR bayonet connection Attachment to optics: clamp with quick adjustment lever Body material: aluminum Material of moving parts: hardened steel Inner finish: grip surface protecting the optics Color: black Required accessory: Rusan MCR connection adapter compatible with the used front device Size meaning: external diameter of the optical sight's objective housing at the mounting point Country of origin: Croatia Available variants MAR-57: 57 mm, MAR-58: 58 mm MAR-62: 62 mm MAR-63: 63 mm MAR-64: 64 mm MAR-65: 65 mm Included in the set Rusan MAR modular adapter clamp in the selected diameter The MCR connection adapter compatible with the front device and other accessories must be selected separately if needed. Frequently Asked Questions How to choose the correct MAR clamp diameter? Use a caliper to measure the actual external diameter of the optical sight's objective housing exactly at the spot where the clamp will be attached. Do not choose the adapter based solely on the scope's designation, such as the nominal 50 or 56 mm objective diameter. Is the MAR clamp sufficient for installing a front device? Generally, no. The MAR clamp is attached to the optical sight, but on the front device side, a Rusan MCR connection adapter suitable for the device's thread and construction is needed. Can the MAR clamp be left attached to the optical sight? Yes. One advantage of the modular system is the ability to leave the clamp on the scope's objective housing and remove only the front device with the connection adapter. To protect the open clamp, a suitable adapter cover can be used. Does a 62 mm MAR clamp fit a scope with a 62 mm objective? This depends on whether 62 mm refers to the actual external diameter of the scope's objective housing. The objective diameter in the scope model name usually refers to the lens's nominal diameter and does not indicate the external size of the housing. Can the same clamp be used with multiple front devices? Yes, if each front device is equipped with a suitable MCR connection adapter compatible with the MAR system. However, the mechanical and optical compatibility of the devices must be confirmed separately before use. When is the Rusan MAR modular adapter clamp the right choice? Rusan MAR is suitable for users who want to quickly attach a thermal or night vision front device to the optical sight and remove it after use. The clamp can be left on the scope, while the front device is connected via the bayonet only when needed. The modular system is especially practical when using several weapons or front devices. Each scope requires a MAR clamp of the correct diameter, and each front device requires a suitable MCR connection adapter. Expert recommendation Before ordering, measure the objective housing of the scope with a metal caliper in at least two directions. The measuring point must be cylindrical and long enough for the clamp to rest on the entire intended surface. Some scope housings may be conical or contain control knobs, rail mounts, or other protruding parts that affect compatibility. Install the clamp according to Rusan's instructions and adjust the clamping force so that the adapter stays firmly in place but does not excessively compress the optics housing. After installing the front device, check image alignment and confirm the actual point of impact at the shooting range. After removal, protect the open bayonet connection with a suitable cover. Quick connection between optical sight and front device The Rusan MAR modular adapter clamp creates a precise bayonet connection on the optical sight for a thermal or night vision front device. Six available diameters, a quick-release lever, and interchangeable MCR connection adapters allow you to assemble a modular system suitable for specific optics and devices.
