Black Raptor · System advice Rusan device connectors and reducing rings This family forms the device side of the Rusan system. The clamping sleeve for the scope is chosen separately.
The short buying answer: Don’t choose by a similar name. Interface, dimension, and system side must clearly match.

Our honest assessment With modular adapters, the correct system logic is more important than the fastest purchase. A clean, repeatable connection only arises from confirmed components; a similar thread or a similar device is no proof of compatibility.


Fits well if …
Device, generation, and mount are matched directly on the attachment device..
the rest of the system setup is clear,
you check the assembly free of tension.



Rather doesn’t fit if …
a component is supposed to serve as a universal adapter,
dimensions or generations are estimated,
a stiff connection is forced to fit with force.



Select variants correctly
The variants distinguish M43 x 0.75, M33.5 x 0.75, M52 x 0.75 and bayonet as well as clearly named device models.
Practical consequence: The variant must match device and connection exactly word for word. Clarify any deviation before purchase, not only at assembly.


Trainer and user tip Write down or photograph the planned chain: scope side → clamping sleeve → connector/ring → attachment device. If a transition is not clearly labeled, the selection is not yet reliable.

Limits and safe use Do not use adapters as repair or improvisation solutions. Keep contact surfaces clean, align parts straight, and check locking, free movement, and secure fit of the complete setup after transport and before use.
Technical practical data 7 variants for Nitehog, Nightpearl/Liemke, Dipol, Guide/Night Lux, HIKMICRO Thunder V2, and PARD NV007.
Frequently asked questions How do I find the right variant? By the exact device mount, thread specification, and confirmed system setup. Is a similar thread enough? No. Diameter and pitch must match exactly. Is this a complete adapter? Only if all intended components of the system chain are present. What do I do if the mount is unclear? Have device designation, generation, and connection side clearly checked before purchase.
Is it okay for a connection to be stiff? No. Do not force it; check the cause and the variant. What do I check before use? Fit, locking, free movement, and the function of the entire system.
