So... I went home and took my A7 Atty apart and it does look as if it is a BF atty... There were a couple of issues that I thought could be easily corrected to make it a decent BFeeder
1. Need to drill a hole in the center post for the juice return.
2. There are 2 opposing holes drilled in the 510 connector, however I don't feel that they do squat. Due to the fact that the deck screws to the base and the only hole that I saw was the center juice hole? So a side hole is what may be needed for good air flow.
Other than that it seems like a workable option... With a little "work" lol.

Any other comments on this atty? I have an unmilled RM2 on order, so I'm all set... It's just nice to have options and since I already had the A7 Why not?
