I like Leupold. I have shot them on personal rifles and Army rifles for years. I have only had one Mk4 go tits up and it was returned to me fixed. I had one M8 develop issues and it took a couple trips back to get it working right but they got it sorted out.
That said I have owned NF in the past, used them overseas, and have currently sold all my scopes except one Leupold and one Trijicon (which are in fixed mounts on NULA rifles) and now swap a NF 2.5-10x32mm between my personal rifles that have 1913 rails. As for the backlog I got my scope in about 5 weeks from order when they quoted 12. I haven't had this optic long enough to say exactly what I think of it but initial impressions are it lives up to the NF hype.
