Notorious/strange looking movie guns

Can't believe no one has posted "Heat" yet.
I believe this is an FNC here.

Who remember a movie late 90,s early 2000s used tripod mounted "sniper" system with huge optics, and cable release trigger, and larger than 50 cal., Pulled off Hollywood head shots at extreme long range before long range was cool. Main character catch phrase was "ouch" after making the shot. Know it's kinda vague, but all can remember. Seemed pretty darn cool at the time.
