Colt said they had something like a 120-day inventory of rifles for the commercial market. Unless that goes down significantly I can't see them resuming production for something that's in a saturated market just for the sake of doing so. I would believe Colt will restart production at some point but only if the market conditions warrant it.
Sellers are probably hyping the break in production...if not outright calling it a complete cessation of production forever...to increase demand for their inventory so they can realize higher prices.
The way I see it...everyone who wants an AR-platform rifle or carbine already has one by now. Prices are down across the board from pretty much every manufacturer. We'll probably even see a few companies drop out as few are buying. If the political scene changes and there's fear of bans or confiscations that might come true then we'll see production crank up across the board again. Don't underestimate the power of panic and the companies that can cash in on it like last time.
