I get caught up in this debate for hunting guns many times a year. I go from custom guns in manners mini chassis with TT315P or ZP5 3-15 scopes thinking I need the very best to mirror my LR target guns. In the end, all those ounces add up to pounds and it sucks day after day after day in the woods. I end up back at factory light weight mountain guns and just bought four of the Razor LHT scopes to swap on the hunter guns. (And I havent been much if a Vortex fan over the years) No they arent even close to the quality of the TT or Schmidt or other real high end scope. But they track true and I can still shoot 1000 yards without issue with them.. Everyone else in camp still kills with 500 dollar rifles and 200 dollar scopes. I'm in the reality check mode where I'm scaling back the hunting gun weight and optics. Im still buying quality scopes in that 800 to even 1400 range for them, but some of these scopes really aren't worth the weight for me for humping around the woods.
If your building a lightweight hunting gun then stick to the plan. The March is good option of high end, but still light. The Mk5/6 has a following. Vortex, Swarovski, etc.
