Looking at my Poly double underfolder I don't see a separate trunion. Looks like the underfolder hardware is just installed in a hole in the reciever rear. Are the Poly's or all Chinese built different than the Eastern European underfolders?

I'll post it again. Stamped Chinese underfolders do not use a trunnion to support the function of the stock mechanism. The Chinese found the extra thickness of their receivers eliminated the need for one. The rivets that you see at the rear of the receiver is simply a small trunnion used to support the recoil spring assembly. In this respect the Chinese underfolders are indeed different from European counterparts. |
