I have one on a Kimber Montana .223 rem. The short eye relief is no problem on that light recoiling rifle and the adjustments appear to be precise. I will say the optical quality is just a little better than poor especially at the highest magnification. You can get the reticle sharp and clear but no amount of adjustment will get the target in good focus and it appears it is more an issue of glass quality than focus mechanics.
I will say the optics are good enough to get the job of shooting game done just fine and if the scope holds zero over extended time I will keep it.
