Question about Quantaray 70300mm f456 AF DI for Nikon
Lens works perfectly.The problem I have is when you set the the lens barrel between 135mm & 210mm the lens barrel will tend to slide on it's own towards 135mm pointed upward & 210mm pointed downward.

Slide a piece of paper partway under the ring (make sure you leave enough hanging out so you can remove it later) and see if that tightens the action some.
Another low-tech approach is to push the ring to expose the inner barrel, then attack one or more pieces of Scotch tape or masking tape.

Right now you are on the "Free" side of the list. I'm an independent not associated with any of the camera, lens or accessory manufacturers I'm a Freelance Photographer that uses this equipment to make my living. Repairs to a lens like this if it were in Canada would run about $120.00 but I'd be asking Ritz cameras first if there were a warranty. If the lens is working for you and you are satisfied with its performance then It's up to you if there is no warranty and it's a pay to repair deal. What I would be asking myself is why is this lens barrel sticking and my answer would be dirt. Lint and oils from our hands will enter the lens barrel and cause all sorts of problems. Also if you use this lens in the field there is sand and other environmental nasty things that get in between the two barrels. I see a lot of questions about these Quantaray lenses, never used one so can't really voice an opinion except that non of the lenses I've owned over the past 30 years have ever stuck because dirt has entered the lens.
