To me, it looks like a re-sniper.
Original rifle looks to have been a sniper. The mount is missing rifles serial number. Looks like somebody stamped the scope's serial onto the mount and barrel to try to make it look legit.
I could be wrong....maybe there was some imported that had the wrong rifle serial number stamped on the mount. IDK.
Here's what it should look like, as far as I know.
I do think some mounts were stamped rather than electro penciled; but, the ones I've owned all had electro pencil.
