I had one of these. Simmons mag44 6-20x.
Complete crap.
The glass looked like you were looking through a dirty glass, and the accuracy on my rifle went to crap. I was trying to figure out what was going on when I Sh1t you not I actually saw the reticle vibrating after a shot.
The scope was FUBARed. It now sits in a box somewhere awaiting my attempt at the famous Carlos Hathcock through the rifle scope shot.
I ended up putting a $200 Burris Fullfield II on that rifle. Works great. The glass is excellent, so is the tracking and the accuracy on my rifle is what it should be.
In case I left any grey area in my post. Don't buy that piece of garbage!!!
