I am just gowing to sit around and wait a few weeks. Local gun store supposedly has more 15's and 10's coming in second week of Jan. We shall see if they actually get them, but they will not be jacking the prices up on them.
I emailed a small LGS that I've dealt with in the past. He told me his distributor(s) have jacked their prices 75% since his last order. Imagine paying $1800 for a run of the mill Bushmaster or Windhem.
It may be quite awhile, if ever, for prices to recede if this is typical and people keep buying at these inflated prices.
Assuming the new ban fails (and given that Feinstein is calling for all grandfathered "assault weapons" would have to be registered under the NFA, I'm pretty sure it will), the market will soon stabilize. It will take a while as the panic subsides and the supply starts exceeding the demand again. Once that happens, prices will fall.
But this isn't going to end in a few weeks unfortunately. I imagine we'll be looking at this nonsense for a few months, unless the bill is brought up almost immediately in January and is utterly destroyed in a bi-partisan "No way in hell" vote.
Sadly, I have a feeling it will pass the Senate and fail in the House by a small margin, meaning they will keep trying to ram it through.
