I'm hearing that black rifles are also getting both hard to find, and expensive. I see Ranier Arms has LMT M4s for $1273, but that seems like an aweful lot of money for an entry-level rifle from a decent company. There are some lower-end rifles in the $700, but I don't see much from the top brands for less than the LMT.
Bravo Company is backordered on all complete rifles, although they do have some uppers, starting at $500 for 16" uppers without handguards, $420 for 11.5" uppers if you're allowed to build a short barreled rifle.
Palmetto State Armory has some rifle kits, starting at $580, but the cheapest AR complete rifle they have is $830 for an S&W with no sights, and 1 in 9" twist barrel.
I'm getting tired of this. Every time there's a presidential election, prices go up, and inventory goes down.
