Maxim was selling them in hardware stores for $3, IIRC what I read about them a few years ago. NFA put him out of business.In South Africa, the same suppressors sold in the US by the same companies, are under $200 and sold over the counter.
Friend and buddy bought one each for their safaris and threw them in the trash when leaving so they didn’t have to put up with the US bullcrap.
Talk about getting ripped off by the suppressor dealers!
