Lost in Idaho...
I need help possibly identifying this random detachable bottom metal I acquired years ago through some trades and what not. I do know its for a R700 footprint, the bolt centers line up with some factory bottom metals I have.

Im looking to ID this thing because I want to send it off with a factory Bergara Ridge stock and have it inletted to fit. Its easier to know if the shop can do the work if I know what I have before I send it off. Its all aluminum and seems to be well made.. Thanks for any potential help.
