I was curious if anyone here had any experience with the new Aimpoint 3X-C magnifier. I want to invest in the highest quality magnifier I can afford for my HD rifle to place behind my T2, but the 3X magnifier is very expensive around $800. I want the magnifier to be durable to be able to use in classes etc., and wanted to see if the 3X-C was good to go or if I should hold out and save up for the 3X (or even 6X - is a 6X too much magnification for a 5.56 AR?). Is there a big difference in durability, glass quality between the 3X-C and the 3X? I would greatly appreciate any advice & like to know what you guys think. Thanks.
