The Rusan MAR-SH-48 modular adapter is a short version of the quick-release clamp from the Rusan modular system, designed for mounting thermal and night vision add-ons to riflescopes with an objective tube outer diameter of 48 mm. The shorter clamping section is useful where there is limited space on the objective tube for a standard clamp. To connect it to a specific add-on, a suitable MCR ring (connector) is required, sold separately.

Key features
- For riflescopes with an objective tube outer diameter of 48 mm – this is not the lens diameter stated in the riflescope's name.
- Short clamp version: clamp length of 24 mm according to the manufacturer's data (the standard version is 37 mm).
- Quick-release clamp from the Rusan MAR modular system.
- Works with add-ons via interchangeable MCR rings, matched to the add-on model.
- When changing the add-on, you only need to replace the ring – the clamp can remain on the riflescope.
- The same ring system as in standard Rusan modular adapters.
Compatibility
The adapter fits onto the objective tube of a riflescope with an outer diameter of 48 mm – measure it with a caliper before purchasing. A full set requires an MCR ring matched to the add-on, e.g. MCR for Pulsar Krypton and Proton, MCR for Pulsar Forward F455 (4 pins) or MCR-M52. The MAR system also offers a 2.5x magnifier with an adapter for the Rusan MAR modular adapter. The rings are described as components of the MAR system – we have not confirmed compatibility with the Short version in the manufacturer's documentation. If you are unsure whether the accessory fits your device, contact us – provide the device model, and we will check the compatibility before shipping.

Frequently asked questions
How does the Short version differ from the standard MAR-48 adapter?
It has a shorter clamping section – 24 mm instead of 37 mm – so it fits on a shorter section of the objective tube.
Is the adapter sufficient for mounting the add-on?
No. The clamp must be connected to an MCR ring suitable for the given add-on – the ring is purchased separately.
Is 48 mm the objective diameter of the riflescope?
No. It refers to the outer diameter of the objective tube, which should be measured before selecting the adapter.
