Prices are going down, down, down. PSA just sold a complete AR-15 kit for $299. Add a $39 lower and you have an AR-15 for $340 plus shipping.
Wal-Mart caved to the pressure and is selling ALL black tactical/scary looking stuff. This includes AR-15's, tactical Ruger Mini-14's, tactical shotguns with short barrels, AR-15 accessories, Surefire weapons lights, etc. They sold out of every Colt 6920 in the country at $699 in just a few days. Anything that was left was marked down to 50% off a few days ago, and was quickly snapped up. I bought a $300 Surefire X300 Ultra pistol light 50% off for $155. They even marked down the .223 ammo that has pictures of AR-15 rifles on the box (Federal MSR, for example)
Wal-Mart CEO has stated that they will only carry common "hunting" rifles and shotguns from now on. It's a shame really, because they kept the local gun stores in check if you wanted an tactical style rifle or shotgun. Wal-Mart sold the same exact thing as your local gun shops for several hundred dollars cheaper in many cases.
