Eight guns -- including a sniper rifle custom-made for Seal Team 6 -- were stolen from Alamo Tactical.
Owners say the gun shop was burglarized by two thieves wearing masks and dressed in black.
"At about 5:20 a.m., two people broke in through the front door. They pried the front door in three to four seconds," said store owner Chris Anda.
The thieves were in and out in of the store in two in a half minutes.
"They had definitely been in here (before)," Anda said.
Anda estimates the worth of the stolen items at about $15,000-$20,000.
"It's frustrating that someone might be out there doing something bad with something they stole from our place, but it's nothing we can do something about," Anda said.
The stolen sniper rifle was one-of-a-kind.
"They only make 14 of them in a year. It's an expensive rifle, a bolt gun custom-made for Seal Team 6 and it retails about $7,000," said Anda.
The suspects were last in a dark-colored vehicle, possibly a Nissan.
