In the area and frankly in Texas in general, I'd send my AR to Benny Hill at
Triangle Shooting Sports. He's in Corpus Christi, TX. Unfortunately his website is down right now. So check back in a day or so.
Benny is an IPSC Grand Master pistol shooter, a champion 3-Gun shooter and gunsmith to many of the top shooters in the sport. He can anything that you want. From tactical to competition he'll get you taken care of. And frankly for the quality of work that Benny does, it's incredible he makes any money, 'cause his work is VERY affordable.
There isn't anything that he hasn't thought about or done when it comes to a firearm. So drop him a line.

P.S. Just before posting this the website is back up. Go figure....probably a problem with my computer.
