KSC BATTLE ARMS BAD Gas Blowback HAO Receiver

This is a gas blowback gun featuring a BATTLE ARMS receiver made by HAO, incorporating a KSC internal unit.
RWA previously released a limited edition BAD gas blowback, but a BAD gas blowback with a HAO receiver, known for its quality in training rifles, is quite rare. (I personally use a training rifle and wasn't aware of this gas blowback model.)
Currently, I've found only one store in Japan that handles HAO gas blowback receivers, and they are quite expensive (around 100,000 yen).

This item was purchased from an auction previously held by a certain airsoft field in Ikebukuro.

It has been used once in a game after purchase.
I disassembled it for a light internal cleaning and greasing, but the operation is a bit stiff, possibly due to the steel heavy-weight bolt. (The recoil is intense, though.)
I bought a new reinforced recoil spring, but haven't installed it yet, so I'll include it as is.

The HOP-UP's effectiveness is somewhat unstable, likely due to the deterioration of the packing, so I recommend a complete overhaul, including the main unit.

The configuration is basically a replica, but the grip is a real BAD part!
It also features a replica charging handle, which is unusual for KSC models!

However, it has noticeable scratches and dirt, so I recommend it for overhaul or parts harvesting. It's not recommended for beginners.

Accessories include three green gas magazines and four CO2 magazines. Two of the CO2 magazines have cracked lips.
*Two of the green gas magazines were reported to have gas leaks by the previous seller, but I haven't confirmed any leaks in my environment.
*Please consider the magazines as bonus items.

The muzzle velocity measured with a CO2 magazine was just under 80m/s with a 0.25g BB, which is within domestic legal limits.
*The previous seller's measurement with a green gas magazine was 75m/s with a 0.2g BB.

Please note that shipping may take some time due to my work schedule.

Due to the nature of the product, please accept it as no-claim, no-return, no-refund (3N).
*If you wish to have it shipped to remote islands or Hokkaido, please consult me first. (It cannot be transported by air & shipping costs will be higher.)
