I finally decided to put a good quality optic on top of my Model 11 non accutriger (gun was purchased new in 06 so I believe that it is a round back receiver). The optic that I chose was the Vortex Viper HS 5-15x44 mil/mil scope. Now I need a one piece base and some rings for it. The bases that I was looking at were either the EGW 1 piece 0 MOA (around $40)or the Weaver Tactical extended multislot 0 MOA (around $30). What's the verdict on either of these or are they just about the same? I'm not sure where to even start with rings there are way too many options. So opinions are greatly welcomed.

Thanks
