Some 760's are real rattle traps. All depends on whether or not the o-ring is still there.
Right ..... That rattle is an easy fix. Slip on a new o-ring and you're GTG.
But that's not necessarily an easy decision either. The O-rings eventually tear and any good PA gunsmith will tell you pretty much the only time they see Remington pumps come in is when the O-rings have tore and then bound up the pump handle. A lot of guys don't want them replaced for that reason.
Hmmmm ...... I've never heard or experienced that before, but can see how it would be a problem. When I replace those rings, I always clean out the forend tube and lightly lube it with lithium grease. Not sure it that helps in the long run but it does run smoother.
I have a 7600 now that has the smoothest forend/action I've ever seen. If you stand the rifle upright and hit the forend release button, the slide will fall almost to the back of the action on it's own.
