Who actually owns GAMO, BSA, BSA Optics, AfterMath, Stunt Studios, and Laser Gen

OK, so I sent an e-mail to BSA Optics asking for help identifying knock off scopes on eBay (they just didn't look right), and the e-mail I got back, while informative, was surprising. It contained the logo's of:

GAMO Outdoor USA
BSA Optics
​BSA Gun USA
Laser Genetics (Night Vision)
​After Math Airsoft
​and - Stunt Studios.

​If you follow the GAMO logo link (http://www.gamooutdoorusa.com/), it shows all of the above, plus Joker Knives.

​That means, they are all GAMO subsidiaries. I had no idea that they were all related in a single corporation. Am I just dense, or did anyone else know they were all a single corporation?

Thanks
