Detailed product description
Rusan MAR (modular adapter) is a two-piece system by Croatian maker Rusan-Mikron: the MAR adapter fits the scope objective, the MCR reduction ring fits the clip-on. Twist the clip-on on and lock it; removal is just as quick – the adapter stays on the scope. Holds zero, no re-zeroing after refitting.

How to choose the right adapter size
Adapter size = the outer diameter of your riflescope objective (the tube at the objective end), not the number in the scope name. E.g. a Meopta 3-12×56 has an objective outer diameter of 62 mm, so you need a 62 adapter, not 56.
- Measure the objective outer diameter with callipers, to a tenth of a millimetre. A ruler is not enough.
- Pick the adapter of exactly that size. If your size is not listed, take the next larger one – it tightens down.
- Not sure? Send us your scope model and we will pick it for you.
