Not a movie, but I was watching Arrow on the CW and Deadshot had some kind of full auto pistol as a wrist bracelet. Seems hard to aim but he had superBG skills. Wonder what kind of hardware they made that out of.
Silly point, Deadshot used a 7.62 and Arrow mused that meant Russians. Why? Wasn't an AK type platform. Didn't say 7.62 by 54 or a 308.
