Ironsighter 1-Piece Weaver-Style Scope Base question

[HankC]

Has anyone tried Ironsighter 1-Piece Weaver-Style Scope Base, Savage Short Action? Any experience? It is aluminum, but seems to be beefer than B-square 1 piece scope base. I espeicially want to know if the slot spacing is weaver/picatinny spec that I can mount scope from other rifles with pictinny rails such as AR flat top.

Know the answer to my own question. Ironsighter sent me a reply e-mail and said the slot spacing not necessary picatinny/weaver spec. Too bad, it is a well constructed base, but I have no reason to go with 1 piece unless I can use same scope on multiple rifles without moving the ring.
