Mil ranging 101
Compare it with a 50mm VXIII and see how it stacks up in weight, I guess. They're also significantly cheaper than the cheapest "other" Mk4's. By a long margin.
Look at the weight of them compared to say the 4.5-14x50 Mk4 LR/T, much much lighter. I suspect they're basically a VX-III 4.5-14x40LR with target turrets and a black objective ring.
They're not "real" Mk4s, incidentally.
But that range is fine for an "all-rounder" and they should work fine.
