Ive decided that my first venture into the NFA world will be an omega 9K since I mainly just shoot 9mm pistols and have recently gotten into 300blk. What would be the easiest way to go about this... I understand that going to SSP and using a kiosk would be about as simple as it gets. When I called SSP they just told me to buy it from silencerco and then come use their kiosk. When I look at silencerco's site they act like I need to go to a dealer for purchase... Could I buy from somewhere online like silencershop then go to SSP to use the kiosk?
