Obligatory shoutout to Front Range Precision. He hooked my up with my Origin. Great price, service, and had everything in stock. For factory prefit offerings it seems just about everyone offers a prefit for the Origin actions. Easy to get another bolt head if you decide to add another barrel down the line in a different diameter. Zermatt stands behind the actions too, pin for my pinned recoil lug snapped after a number of barrel changes, they had some new ones out to me the next day.
