This is a great sight for someone who wants a good sight for a good price.I installed this sight on my Ruger MKlll678 target and had it driving roofing nails at 25 yards after only 7 shots. I found the repeatability after removing the sight from the gun and reinstalling it was extremely close to "boresight" without further adjustment. This is a very nice sight for the cost.
Pros: Easy to sight in. Nice brightness range. Single base connection bolt.
Cons: None I could find
