Tokyo Marui M4A1 Electric Airsoft Gun

Tokyo Marui Electric Gun, 18+
This is an M4.
It is a domestic manufacturer product, not an overseas one.
This is an airsoft gun made of resin, not metal.

Last month, I mistakenly bid and won the auction without being able to cancel it, so it has only been displayed and its operation has not been confirmed.
What is shown in the pictures is everything included.
There are many GBB M4s from various manufacturers, but I don't own any electric ones, so I don't have any batteries or magazines. Therefore, I have not been able to confirm its operation even once since purchase. For this reason, please only purchase if you are able to repair it in the unlikely event of a malfunction, or if you plan to display it as an object.

I don't know the manufacturing year, but I believe it is an older model.
As it is a used item, cleaning, greasing, and replacement of parts like the hop-up bucking are likely necessary.
Please only purchase if you have knowledge and technical skills regarding electric guns.

When I disassembled it, I saw the motor inside.
The piston does not move, so I believe it is a standard model, not a next-generation one. (I know nothing about electric guns.)
I also have no idea about compatible batteries or magazines.

There is no box, so it will be shipped wrapped in bubble wrap.

Please confirm once again that only the main unit shown in the photos is being sold.

If there is no response to my reply after you have commented, and 24 hours have passed, I will block you to prevent trouble, as there are cases where buyers do not confirm receipt after purchase or cannot communicate via messages. Please understand.
