Listen to the shots againIt is illegal, all automatic weapons made after 1986 are illegal for private citizens. Pre-86 weapons require registration, extensive FBI background checks, & approx. $20k to pay for the process
edit: just read the bump fire link, no idea if that's illegal but I doubt that's what was used.
People saying that if you buy the gun stock with bump fire it is not illegal
Again I'm just repeating what I've read so far and know nothing about these shots
Shouldn't a full auto be consistent firing?
