If you cant or wont spend the money on a higher end scope (which I dont know how really neccesary they are) the mark 4's are a dang good alternative. IMHO, they are very practical for most LR applications. I use a Mark 4 (original version) Fixed 10 power x 40mm and LOVE it for my sheep hunting rig. It offers extreme durability for the rugged bumps and bangs and positive adjustments, good optics but is considerabley less bulky and is much lighter than my NF's. Most of my sheep are nailed at 600 yards or less so I dont mind the 10x. With a little practice I was and am able to get on target at 25 yards without any trouble even for it being a fixed 10x.
