I have 1 two piece base on one of my guns only because I had to do it that way.
I feel the advantages of the 1 piece out weigh any negitive aspect someone might try to come up with.
As far as scope height negitivly affecting the accuracy of a rifle. I doubt a single person on here no matter how good they think they are (Me included) are not going to notice the affect of a 2" scope height over a 1.5" height.
There is a picture in that thread that shows a pistol with a special scope mount that is 6" tall I believe.
Want to put an Aimpoint on a Ruger rifle. - THR
I like mine low because I like the way they look. My 308 (2 piece base) is goign to get a new stock in the next year. This stock will be built for how high I have the scope mounted now.
