The MK 6 is great at 6x but a fail at 1x and it cost Kahles money. FFP and exposed turrets make no sense to me on any 1x optic.
At this point, if you need a serious use 1-6x you either accept the weight of the Vortex Razor or accept the cost of a Kahles or S&B.
Third choice is the Bushnell Elite Tactical 1-6.5 SFP or go 1-5 with a Steiner.
