Events like the 94 AWB, Y2K, 9-11, Katrina and now the Obama election have increased the gun owning populace of the US. This will make it more difficult for POTUS to push through a new AWB, ammo tax, ect. to pass. (this is assuming he even want's to take on this fight)
With the Heller Supreme Court decision, a total ban seems improbable.
That's the way to act. Buying up stuff right now at double last year's prices doesn't help. Watching what local/state/federal government is up to and making legislators aware of your stance via articulate, sane handwritten letters (ie avoid mention of "blue helmets" etc) is about the best you can do for the cause.
At the DFW area gun shows semi auto rifle prices have reached about double what they were on Nov 1, but I really don't see them selling at that price.
Went to Cheaper Than Dirt the other day, and they said the cheapest/least expensive AR they have would still run me $1400 for an A2 style upper and collapsable stock. They had an A2 style rifle with solid stock and 20inch barrel that they wanted $1800 for. I know that Cheaper Than Dirt isn't exactly all that cheap, but still, those prices seem a bit up there. And the counter was no where near as busy as it has been in the past months since the election.
They had plenty of rifle ammo, not a ton of hand gun ammo though. Cabelas had tons of ammo, and the counter was packed. Prices seemed pretty straight on there, but they don't carry evil black rifles. However, ammo price were good, so I picked up a few boxes of .40S&W Hydrashocks and a box of Federal "Law Enforcement" hollow points.
