Purchased for new gun. Appear to be well made. Due to poor weather haven't tried them out yet but should work well.

BUIS

Work pretty well for the price point. Never could really get them zeroed in. Rear sight worked great. Couldn't get the front sight to adjust very well even with the sight tool. Still needed about 4 clicks down. Could see the adjustment was there just couldn't get the sight post to turn. Other than the front sight I would have given it 5 stars. So now I have to remember I'm high by 8 inches at 100 yards.

Good morning Garry, We're reaching out via email. We're sorry for your experience thus far, but we'd like to get this corrected ASAP!
