No they weren’t. They were designed for disabled folks to use on their pistols. Just because some may use them as stocks doesn’t make them one.Anyone who has ever used a credit card is on file. Information is power and valuable. Google and the credit card co’s and bureau’s make billions with our spending habits and such. And trust me, there is no anonymity anymore, not here or anywhere. Screen name be damned, lol. Google your screen name and most likely it comes up. So I always caution my friends and folks to not post anti .gov, President , and policy rhetoric. We aren’t as anonymous as we think. Not in a nearly cashless society now.
Again, we have brains and will power to do what we like. I imagine there will be a modification of the brace details but who really knows. The braces were a funky step that clearly circumvented the sbr law anyway.
