I’d use the airsoft because there is an almost 0 chance of an accidental fatality due to dummassity.
Seriously, the left totally missed the boat on airsoft.
The replicas are set up to feel and operate very similarly to the real thing, enough to train young people so that when they are old enough, they can graduate seamlessly to the real thing.
Since they couldn’t afford the fake muzzle flashes, they probably wouldn’t be able to figure out how to put up a blue screen at an actual firing range. It would take all day to get all the right angles.
They probably made that movie in a week. lol.
