Re: S&B 5-25 scope rings needed for an AE MKII
Your AE has a 0 moa pic rail, if I'm not mistaken. In this case, I would say that you should get the AI 45 moa pic rail mount for this scope. It was designed for this scope, from what I have been told.
If you go with an 18 moa mount or a 28 moa mount, the mount will need to be machined for clearance of the large erector housing in the 5-25. The 5-25 has enough travel that neither of those are the correct options anyhow.
The AI mount is less expensive than some quality rings out there, and I have never had one mar a scope (Badger rings did, on the other hand.)
