Choose the right Rusan adapter for your thermal or night vision device. Compare the eyepiece adapter, modular adapter, and Weaver rail to match your setup.
Quick Answer
Choose a Rusan eyepiece adapter for Sytong and Pard NV007A/V clip-ons, a modular adapter MAR-S for thermal or night vision add-ons, and add a Weaver rail when you need to mount an IR illuminator or accessory.
Eyepiece vs. Modular – What’s the Difference?
The Rusan eyepiece adapter is purpose-built for Sytong (HT-66, HT-77, HT-88) and Pard NV007V/A devices. It uses a bayonet mount and an adjustable quick-release clamp to fit eyepieces between 40.5 mm and 47 mm. This eliminates the need for tape shims. It does not fit Pard NV007S or SP models.
The Rusan modular adapter MAR-S, on the other hand, is a clamping system that connects thermal or night vision add-ons to a daytime optic. It uses a single screw and comes in multiple diameters to match nearly any objective lens. If you switch between devices, the repeatable clamping design helps maintain zero.
The Weaver rail accessory adds a mounting point for an IR torch or other accessory. It attaches to any Rusan clamp adapter via two screws and is available in three heights (9 mm, and others) to adjust the distance from the optical axis.
Decision Rules
- You own a Sytong or Pard NV007V/A: Get the Rusan eyepiece adapter (product 1952394). It directly replaces tape shims with a quick-release clamp that fits eyepieces 40.5–47 mm. Check your eyepiece outer diameter before ordering.
- You use a thermal or NV add-on with a daytime scope: Choose the Rusan modular adapter MAR-S (product 1952404). Select the diameter that matches your add-on’s objective lens. Measure the objective diameter; if it’s not listed, the adapter may not fit.
- You need to mount an IR illuminator or accessory: Add the Rusan Weaver rail (product 1952406) to any Rusan clamp adapter. Pick the height (9 mm or others) to align the accessory with the optical axis. Use the lowest height that clears the scope body to keep the setup compact.

Who Should Choose Which?
Best for
- Sytong or Pard NV007V/A owners who want a tool-free eyepiece adapter
- Shooters using thermal or NV add-ons who need a repeatable, zero-holding clamp
Not for
- Pard NV007S or SP users – the eyepiece adapter does not fit those models
- Those who need a permanent, one-piece adapter – these are modular and can be adjusted
