Depends on how accurate you need to be...the first one got great reviews if you read them. I prefer a traditional scope because the aiming point does not cover so much of my target.

Scope number two of your pick substends to 5 MOA meaning the aiming point you see in the 'scope covers five inches at 100 yds. I need mine much finer than that. For typical hunting you would do with a 22 lr and the gun you have you can do excellent with your first choice.

Scope will fit a standard Weaver style base. No 10/22s have a machined in groove they have a Weaver style base that is screwed to the action. Your answer is yes the scope of choice will fit the common weaver base that comes with a Ruger 10/22.
