So I've been offered the previously mentioned mk4 for 450, box paper and decent rings. I don't NEED another scope, and it's edging my spending limit for a while (and I had a .357 that I wanted). BUT a buddy of mine has a higher power mk4 that I've used for about 30 seconds and liked. So I'm waffling on buying this one, to go on my 7mag and moving my Athlon to another rifle. What do you guys think?
