M924 DMP-9 submachine gun replica ETU Wireless [DE]

I'm selling my M924 DMP-9 submachine gun replica ETU Wireless [DE], purchased from Taiwan Gun in November. The original hop-up bucking was immediately replaced with a Maple Leaf Macaron 50°, and the spring was also changed to bring it below one joule. I still have the old M90 spring. The replica has only been used once, works perfectly, and is completely new.
