That is strictly a rimfire action and bolt assembly. Centerfire has a much larger loading/ejection port and the locking lugs are located at the front. But I can believe Dave told you that based on past experience.This one showed up as a rimfire. Supposed the get the centerfire bolt in 2 weeks. When that shows up, I’ll put a barrel on it.
