I know they are very different, just looking for a reliable long range hunting scopeThose are two completely different scopes. One is 34mm FFP, the other 30mm SFP. The credo is 7ish oz lighter. If you want FFP and a heavier scope with more internal adjustment go with the Burris, if your counting oz's and want SFP go with the Credo.
That XTR3 has some QC issues according to a bunch of forums I've seen recentlyThese are the 2 scopes I'm currently looking into for my hunting rifle, any word on either of them?
