There's a new gun store that just opened last week in the former Freedom Munitions space near Jersey Village on Jones Road. The store is called Texas Underground Armory. AR magazines with custom printed logos, a fair inventory of pistols, black rifles and shotguns. They seemed to have a decent inventory of the more in-demand ammo (5.56, 9 mm). If you live in the area, you should check them out.
