I have just acquired two Chinese underfolder stocks. I am looking for a little input into their installation. These will be for future use, but I wanted to get familier with them and have any missing parts on hand for when I am ready to use them. I know that the Chinese didn’t use rear trunnions and the 1.5mm receiver added the needed thickness so I might do these on the GT 1.6mm receivers. A few things really struck me as odd and it seems like there are a lot fewer parts on the Chinese pivot assembly. These were test fit using a Yugo rear trunnion from another kit.
First thing:
Do the Chinese lock when in forward position? Mine never did lock and went what looks like to far up.
Second thing:
I think this is normal, but look at the low angle when locked open.
Third thing:
This is how it went together, and worked. Is this correct for a Chinese?
Forth thing:
Also notice the hole for the pivot assy. lock pin. It is horizontal, every other UF I’ve ever seen, the pin went in vertical. This can’t see how this could be correct but has to be turned this way for the latch to slide with the pushbutton.
Fifth thing:
What is this part? Is it for the Chinese UF? It’s sure don’t fit anywhere I can find to put it.
Sixth thing:
Is this it. Is this a complete part set for the Chinese UF setup?
I appreciate all the info. I have never seen a Chinese setup and just wasn’t sure.
