Walther WA-2000 used by James Bond
Owned by MI6
Featured in The Living Daylights (1987)
This rather big and hefty gun had an infrared sight with a telescopic lens. Saunders gives Bond this gun to shoot the would-be assassin, Kara Milovy. Bond is offered the choice of ammunition, between soft nosed bullets or armour piercing ones, he chooses the later mentioning KGB snipers usually use body armour.
When the sniper appears at the window, Bond notices that it was the girl with the cello he noticed earlier. Noticing that she was only an amateur and "doesn't know one end of the rifle from the other", he merely shoots the gun out of her hand rather than kill her. §
