I'm just looking for a place to buy accessories like flashlight adapters, stocks, and that kind of thing. I'm more of a brick an mortar shopper than an internet shopper. It's also easier to meet other shooters that way. Thanks for the advice!
The Cabela's by me has a few things in stock. The Gander by me sells AR's, but doesn't stock any accessories.
I'd check the Hometown forums over on ar15.com. I know the PA section lists a bunch of AR friendly local shops. I've tried one of the small shops here in Central PA and they had NOTHING there... But maybe you'll have more luck around you.
