Does anyone know where I can find an exploded view of the ZKK-602 receiver? Don't ask me why but I took the pop-up rear peep sigt out and I may have lost a part.

I had a couple of these ZKK rifles with the pop-up sight. So here, from memory, is what you SHOULD have:

The sight unit complete. A cross pin that holds it into the receiver.

And...depending on the model either ONE or TWO springs that go under the sight unit to give it its "pop up" ability.

Plus, of course, the button you press to make it pop up and the spring with an end on it (I think) that goes behind that. That spring I think fits in a blind hole in the sight unit.

I think that is about all.

But fear not!

All of these parts even the button are EASILY made with just a hand file and the small springs can be substituted with any other spring of the same size.

Thanks for answering. I did get the sight back together and it works. My real question was; is there anything that attaches to the bottom of the spring where it fits into the little depression in the receiver. After putting it back together I don't see how there could be given the amount of space provided for the spring. I can't get on the thread to the Notro Express forums, it just says it can't find it. I think that had a catastophic failure around Christmas time.

If this is the spring that makes the sight "pop up" (and NOT the spring that works the plunger) then no. Nothing.

Certainly on my few ZKK rifles that I've seen with both one spring and two springs there isn't anything else.

Just the spring, the whole spring and nothing but the spring! Or springs. If there were two side by side.

You can tell by the number of holes drilled on the underneath of the sight.
