From people who actually shoot, a survey.
Keep in mind a couple things:
1) They may actually own more than one sample of the scope they reported.
2) These scopes are all something like a 4x or a 1-4x.
3) This is a survey of HP shooters, so the knobs get twisted constantly.
Looks to me like March is a champ, along with Sightron and... Gasp! "Reupold".
You only get info like this from real shooters, not from guys who can't even set up an AR scope and shoot VW Microbus-sized rocks off a backpack.
