One problem with the scope is that the focus knob is "jerky" instead of

to focus and higher magnifications. Is there a way to smooth this? It is
rack and pinion.
Maybe powered graphite?

Thanks for any help...

I'm not sure using graphite around a scope would be a good idea, although
I may be wrong on that. I use a silicon lube like TriFlow on mine - just
be very careful not to get it on the optics!
A sticky focus mechanism might also indicate grit in the r&p. Might be
worth cleaning it thoroughly.

Cheers!
