Tokyo Marui HK Scope Mount Base for MP5/G3

This is a Tokyo Marui genuine H&K Crow high mount base.
It has been stored in a dark place without being used even once.
I am listing it because I don't think I will use it in the future.
It is now discontinued and rarely seen in circulation, so I believe it is a rare item.
The rail position is high, making it compatible not only with scopes but also with dot sights and holographic sights.

The photos show everything included.
