Not sure if this is a rifle the op changed himself, but I'd be weary of a "non cataloged" rifle. So he put a trigger in and changed the stock? (which by the way is NOT a precision stock, nor is it what was on the early pics of the Marksman rifle, the PRS was).
My biggest question would be why is it so inexpensive if upgraded from a 2700 dollar rifle. Yes, it's a steal if it's new, although I would've like the UBR stock.
