I would like everyone's opinions please.

I just got my Rigid Alloys chassis for my BTVLSS and am going to install a Swampfox Optics Patriot 6-24 FFP scope. I am also planning on using the Swampfox Freedom II rings which are 1.1" centerline. With the Sharpshooter MIL reticle, I can use hold overs out to 275 yards (according to Strelok). I don't plan on shooting much past that.

My dilemma is that I don't know which base to go with. I am considering a 0 MOA, 20 MOA or 25MOA base. If I go with either 0 or 20 then it will be EWG and DIP for a 25. DIP is out of stock on the 0 MOA base for left handed MkII's

I appreciate any insight.
