OSOK,
Big Bill and I both have seen these in the gun shops and I agree, they are verrrry impressive (in .308 cal.)!! They look brand new, unissued. Now having said that, I can only wish you well on your decision, because we've all drooled over owning one in 45-70. Maybe if Mikey would jump in here, he will have a few words of wisdom.??
