Almost everything I've seen out there is still pretty over priced but coming out of this squeeze all of the manufactures are still being limited by their component suppliers. This month is a big difference from last month on availability, so hopefully by the end of the summer we'll be through the worst of this mess.
Here is a cool search tool that I have been using to locate ammo and components:
GunBot find 223 5.56 AR-15 ammo in stock
It searches a ton of places like Sinclair, Cabela's, Midway, Palmetto State Armory, etc. for current inventory and availability, even the price.
Check it out.
