Movie question for all you detail spotters..."Sniper 2"

I am watching Sniper 2 with Tom Berenger on Spike ..there's a scene where he goes in an old basement with his female contact after his spotter gets captured to find a weapon. There is a rifle on a bench and he goes to it and picks it ..(Ok here's the question to see if my C&R skills/knowledge are improving) He says "Mauser 7.92 it's an antique but one of the finest weapons the germans ever made" ..thing is I think he's holding a mosin nagant 91/30 looks like a magazine well that leads into the trigger area (mausers are flat right?) the sling is through slots in the butt and the front stock (mausers didn't have a slot in front right?) and the bolt is well it's a mosin bolt short and straight. Anyone confirm? Sad hollywood won't even pony up for a prop mauser.

Edit to add: I'm sure its a mosin noticed it has the finger groove on the stock.
