One of the most iconic scenes in the over-the-top Rambo: First Blood Part II involves the shirtless Sylvester Stallone wielding the M60E3 while firing from the hip. Even those who don’t know guns would recognize it as “Rambo’s gun.” While Stallone’s handling was cinematic, to say the least, it was still a very real weapon that saw use with the U.S. military around the world.
