I was ask about helping out on a build and instead of running a bracket system I suggested this.

This particular spacing is for a double Tac body with both air supplies on the right. (Customer request)
I'm open to doing another narrower setup for ULE bodies with opposing air supplies if there is any interest.
Yes, ULE milling is possible on the whole rail, just keeping it simple for now.
I have not put a lot of thought into sear tripping options but we can discuss it here.
No, I don't have a price yet.
Yes it can be machined for SS bodies too.

I'm currently in the middle of another (undisclosed) project and will see it through before I do much more on this and that is if there is any interest. But I thought we could start a conversation on it and see where it takes us.
