Sightmark red dot - Sightmark Wolverine 1x23 CSR 4 MOA Red Dot Sight

I am relaying this as it was a gift. The recipient was quite pleased with it. This is the 3rd I have purchased, two 4MOA (gifts) and one 2 MOA. All three are great quality and a good value. The 4 MOA's were mounted on AR 15's and with the preinstalled riser when mounted on the upper receiver are a perfect co-witness to the front iron sight. One is being used in conjunction with a flip up/down magnifier as well. The 2 MOA was mounted to a lever gun with the aid of an add on picitinny rail and set with a laser bore sight.
