Anyone have any experience with Areo Solus actions for a hunter rifle build?

There are better options. The solus weighs 36oz without trigger. A defiance classic is about 20oz and only $995.
Both come with a rail, it being removable on the defiance and built in on the solus. The Mac bros evo II is a 26oz and a bit cheaper as well, it was a very nice action when I had mine
