Millet scope - Millett Multi-Dot SP Electronic Red Dot Sight

I messed up and ordered one from another company they couldn't find where I had ordered it.So I ordered one from Optics planet which I received pretty quickly.To make a long story short I wound up with 2 of them.I put one on a Ruger hunter 22/22mag sighted it in at 50 yards dead on.Good round red dot brightness is good and have had no problems.The other one I put on a Walther pellet gun dead on at 25 yards pests don't like it.The main reason I got it is the 1 inch diameter tube fits the rings that came with the Ruger and it is not huge and bulky.Eye relief is excellent at any distance.
