Yet another WK180C Gen 2 issue...

Not sure if this one's already been mentioned. There are so many posted that it's tough to filter through them. Pardon my terminology, I'm most definitely no gunsmith.

I took mine out for the second time today. I put about 100 rounds through it today - about 300 total now. The pointless buffer tube came loose. It looks like they (attempted/pretended to anyway) used a punch to secure the plate at the front end of the stock to the large castle nut behind it, securing it to the upper receiver. Well, they hardly made a mark when they punched it and the, like, 0.05mm of metal holding the two pieces together sheared and the whole thing free-spins now. I tried to repunch it myself but probably not effectively. We shall see after the next trip to the range, I suppose.

Anyway, other victims... err... I mean, owners... keep an eye out for this. Oddly enough, my only other issue (so far...) is mag stoppages with the M2 mag that came with it.
