All perfectly legal to own, no gun registration, no waiting period, no laws about conceal carry (for air pellet pistols) etc-) lots of choices from single shot to large clip guns, to full auto- can even order over the net, no laws preventing it apparently- none of the regulations imposed on traditional rifles- Can even pass them down without the government demanding you jump through hoops to do so- lots to like-
oh, and ammo is ‘fairly cheap’ and readily available for many calibers- once you get into the largest, ammo may be a bit harder to come by- but even .50 cal is popular and pretty inexpensive- if nothing else- they make for good target practice guns- but these things can take down even cape buffalo- they are serious hunting tools
on second video go to the 7:27 mark=- that’s where they start shooting hte beast and show the ammo-
