gun noob here.....looks like it's the same mechanism above the triger as the jyrojet, um maybe it's a jyrojet rifle with a scope? lol.
This one should be easy...
As kind of a sidenote, I got to handle one of those last weekend. Kind of a weird piece. I can't stand the sights on it - I hate the wood in front of the rear sight!
yup same gun but just a rifle carabine^^
