Yes, it's a rifle.  No chop.  I posted some pics on my intro thread.

Didn't really answer the question asked, since there are TWO possible lengths of "rifle" (neither chopped) in that serial range, but, I had overlooked your earlier pics, so, with reference to them, was able to satisfy my curiosity.  Thanks.  :-)
