Bought one and mounted it on a 6.5x55. Glass was great and it sighted in fine. Took it hunting and as the sun was setting, I could not see anything thru the scope due to glare (not even looking in direction of sun). Checked it out the next day along with a couple of other scopes, and it was the only one that showed a real problem with glare on the lens. Ended up returning the scope. This was a sample of one and I do not know if all the Mtacs are this way or not, but I was very disappointed as I really wanted to like the scope.
