Disassemble the CA33KA3 electric gun, which is supposed to be modeled after the Classic Army HK33K, and just the handguard.

The handguard part of the Tokyo Marui G3 series electric gun is disassembled and joined with the handguard part of the CA33KA3.

There’s a little gap…

Next, install the slide stock, lower frame, etc. At this point, I made sure the hop-up dial did not come in contact with the wiring and that I could turn the dial properly while working.

Also, I had to remove the “mech box stopper” on the rear side to connect the wiring. Without this part, it cannot be fixed when the slide stock is extended.

The Nicoichi electric gun is complete.
The overall length was about 712mm (without the stock extended).

This time, the inner barrel used is from Tokyo Marui’s G3SAS electric gun.

The stock brass inner barrel length: 208mm and is short and deep.

Therefore, there is a possibility that when you fire a BB round, it may hit the inside of the gun and not fire properly.
