Extensive Customization - Over ¥100,000 Total - Tokyo Marui Next-Gen Electric Gun M4A1 CARBINE

This is a Tokyo Marui Next Generation Electric Gun M4A1 custom model.
I purchased it as a custom item, but I haven't used it much and have too many guns, so I'm selling it.
Here is the description from when I purchased it:

Semi/Full/Auto-stop and other functions are in good working order.
Both internal and external parts have been extensively customized.

It has been tuned to withstand 11.1v LiPo battery operation.
Batteries and battery chargers are negotiable.
Using the G&G Basilisk 17K high-torque motor provides a cycle (17 rounds per second) that emphasizes sharpness and durability exceeding that of Samakoba. This makes the cycle considerably faster than the genuine model and provides a satisfying recoil.

Furthermore, parts have been replaced to improve durability, allowing it to operate without sacrificing recoil.
