I've had a Sightron SIII 10-50x60 for a while now, but it doesn't come with a factory supplied side-wheel. So I designed one and had it made. I'm getting it this morning and will start setting up and testing it.
I've also noticed it being parallaxed for 11yds only. I was also wondering if you can re-parallax it yourself.
There are quite a few of these scopes used in SA. So far I haven't heard of any failures.
