Re: Leupold M2 or M3 knobs?
If you are wanting more precision, then the M1's would be better since they are 1/4 MOA adjustments. If you want to get out to distance faster, with less turning of the knobs, then either M2 or M3 knobs. I prefer the M3 knobs and have two scopes with these, a 3.5-10X40 and 6.5-20X50 I just purchased from the custom shop a couple months ago. Tac has it mostly correct on adjustments. M1 is 1/4 MOA, M2 is 1/2 MOA for both elevation and windage, and the M3 knobs have 1MOA elevation and 1/2 MOA windage. Hope that helps.
