Re: Leupold M1 vs M3 knobs on Mark IV
The M3 are more desirable if you want to get from 100yds to 1k really fast, counter sniping, and in some aspect hunting. If you were not interested in getting a pinpoint accuracy but more so a hit with in MOA then the M3 would be a good way to go.
I use an M3 on a lightweight setup.
