I had an Alpha Arms 1 for a while. They came after the Texas Magnum, also designed by Homer Koon. It was a nice little rifle....had a very similar bolt, but most were short actions.
I've had two, first a .270 which I traded for this .338-284 Alaskan. It's SS and has a dense laminated stock. The design is unique. The stock has aluminum bedding blocks fore and aft of the mag. The trigger assembly/tang floats behind the rear bedding block.
I understand they used Douglas barrels and this one is very accurate, really likes 160 gr. TSX.
Quality is very high.
And yes, this is a factory chambering.
I'm not using it, too many other projects.
I could be traded out of it, dies, brass and bullets...
Rear express sight has never been cut for zero, is flat across.
