The rifle pictured seems to be mashup of a civilian bolt action hunting rifle (a military rifle of any design would not have a shiny chromed bolt), the frame appears to be aluminum flat bolted together (poorly), a harris bipod at the front. Notice in the picture the frame of the rifle appears on only one side, this would make for a flimsy and inaccurate design. The scope Bourne is using is a Zeiss Victory Diavari series. A sniper's scope would have adjustable turrets clearly marked, and adjustable optic, and probably an illuminate reticle.
