After months of cruising ebay I finally found a pachmayr lo-swing mount with rings. It fit perfectly on my rifle. I cannot get the rings to work with the mount. The rings go on, and I put the little post through the loop tension spring that is supposed to hold the rings in the closed position. I cannot get the loop spring to tension the rings closed. I open and shut the rings a few times and the whole thing goes out of whack.

Is there any trick to getting this thing to work? Or should I go back to the Talleys?

If it's a side mount then you gotta mount it on the rifle first. The spring holds the mount down on the receiver ring so that the little post you see can act as a stop when it bottoms out on top of the receiver. If it's a top mount then I don't know 'cause I've never used their top mount.

There is a set screw that protrudes for the bottom of the top portion. This stops the mount in a positive place. Is it there?

I screwed the set screw in as per the instructions, but there is still a little left to right wiggle. Is the post supposed to be inside the spring loop?

BTW it is a top mount.

If I remember correctly, that little hook-like springy thingy is supposed to snap over the pin to hold it down. And, the screws in the base that control the pivot, need to be tightened a bit to eliminate wobble. I hope I am but it has been quite a while since I saw one of these; my dad loved them.

On my side mount, the spring loop's position is adjustable.

The problem is that the spring loop is fastened to a ring that goes around the pivot of the base. You are supposed to set the spring loop into position to hold the the scope closed and then scre down the set screw. The set screw does not have enough "bite" to keep the ring from rotating around the pivot for very long. Sooner or later the whole thing goes out of whack.
