I have a NIB 12-42x56 w/ npr1 I've been thinking of hocking to get an ATACR. I really could use the extra adjustment since I've been fooling around past 1760 quite a bit lately. Plus the 5-25x is a solid and practical mag range. It's just a beast of a scope. Hope you give it hell and get it nice and broke in. Way too many NFs out there as Safe Queens, status symbols, or just shot 3 times a year.
The 1 moa wind stadia is an awesome upgrade. I do wish they would put a real short mil scale in moa scopes (and vice versa) somewhere out of the way so you can help others out, but people are a little too straightlaced for that kind of jazz.
