I'm afraid there won't be any supply any time soon in Houston, at least at reasonable prices. I saw plenty for $2000+ at a gun show.
One local dealer has a list so long they said essentially:
We have a waiting list, when an AR comes in (regardless of brand or type) they call you and give you 4 hours to claim and pay for it.
I inquired about an FN SCAR, they said at least a year. Their pistol case and shop floor was essentially stripped bare.
TX is quite good for gun rights, but not so great during this rush.
I exist, if for no other reason, to increase the entropy of the universe.
