This hopefully won't stir anything up, but I remember reading that Gibb's used 1903 drill rifle recievers for their reproductions. I'm sure they are safe, but you should definetly look into the rifle more. I also believe that the scope is China made.
One nice thing about Gibb's is they at least have the decency to add mark the rifle stating that its a repro (barrel dates, etc), unlike some other vintage rifle company (Ahem, Michel's Mauser's) (By company I mean organized crooks).
If I had 1k to push around, I would get a used 1903 for $400-600, then get a repro mount/scope <--- easier said then done, might have to settle for something that looks similar.
As a suggestion for scoping: I've been hoping to get a Mauser for quite a while and put a POSP on it. (The following should work b/c the m1903 is very similar to a mauser). This is a pretty simple procedure. All you have to do is purchase a mauser slide rail for the posp, d&t it, slide on the scope mount (can be a weaver centered or a scope/mount combo which will be off sided to the left for right handed shooters). In this case the scope, mount, and rail will cost you about $400. Throw in a little extra if you have a local gunsmith do the drill & tapping.
Best regards.
