We've had 8yrs under democratic rule, and gun laws in most areas have done nothing but get better and less non-sensical. For those of you in liberal states, well, you're F*cked no matter who takes the Federal office.
Frankly, I think the burn on AR's is already starting, wholly driven by those profiting by selling them. If Clinton takes office, the $hit is going to hit the fan in the market for the first year, then it'll settle back down again, just the same as it has for all of these other events in recent years.
The AR industry seems to be taking a lesson from OPEC - control the supply to create the appearance of shortage and drive panic demand, then you can set the price.
Then again, maybe I'm not to worried simply because I have all of the AR's and AR parts I could ever need, so if I end up in a shortage where I just WANT something I have trouble finding, I'll be fine.
