      I was a little nervous about the flip to side 3x scope. But it definitely exceeded my expectations. Multiple reviews said that it was wobbly but mine is perfect. Super tight. Very easy adjust center red dot. Lines up great. Definitely buy this if your looking for this type of combo.

      Thanks for sharing your experience, Lance. We're glad it exceeded your expectations. Cheers- AB

      Top Sight!

      I was extremely pleased with the quality and workmanship of this sight. It is solid, sturdy and dead on the money. I noted two things about the sight, one of which wasn't explained in the literature but customer service did a great job explaining it and neither detracts from a five-star rating. The 3X magnifier doesn't quite line up with the sight if you select the 1" riser but that does not adversely affect in any way the performance or how it works. Secondly, the elevation and windage clicks are 1/4" at 25 yards, not 100 yards. No biggee and the sight works like a champ!!! You will not be disappointed with this sight.

      Thanks for sharing your experience, RIchard. We work hard to meet expectations like , yours, we're glad we hit the mark for you. - AB
