Here's the elephant in the room with the Archangel that no one talks about...
They did away with the bottom metal (obviously), so the action screw- from the top- screws down into a threaded steel pillar.
A steel pillar with blind threads. Really poor design, IMO.
I've seen one report online from someone where this was already rusted- and they couldn't thread the action screw in.
Get that rifle is out in the rain or snow, and water and moisture gets down into the action and fills that pillar like a Dixie cup... There's no way to get the water out...and after a while, the action screw will rust out or freeze in place as well.
I like the work they did on designing a mag-fed stock, but this design flaw will result in a lot of unhappy customers down the road.
