Got one on my 35Rem Marlin - so far so good. Seems clear enough and parallax is set st an honest 100yards.
The vertical adjustment allen head lockscrew for resetting the zero point is a sloppy fit with the key provided, and I don't have any other metric or imperial key that fits better - I don't expect to need to adjust often and it doesn't need to be all that tight, so should be okay.
First scope I bought that didn't come with caps.
