I have an A grade in the 2000 serial number range that is loose. I added a few pieces of scotch tape to the U-section of the barrel lug, and now she locks up tight. The barrels will fall free without any resistance when I push the top tang lever. Also, the barrels will wiggle left and right when hanging from the receiver.

I am not familiar with the piece of metal that is attached to the bottom of the barrel lug. There seems to be a spring underneath that piece. That piece, whatever the correct term for it, is also fairly loose on the barrel lug. Seems like it should be tighter. If I replace the spring, will that yield positive results? Thoughts or experiences are appreciated.
