It's part the of the annual Oklahoma Full Auto Shoot and Trade Show event.
There were 100 vendors, and thousands of machine guns on display for people to see and rent.
You could even go as far as shooting from military helicopters and the firing line..blowing up cars and airplanes.
Organizers say the machine guns are what's attracting visitors from from across the Four States.
Owner of L&L Machine Guns Larry Cheatham says,
"We have everything from World War 1 to the most modern day machine gun out there, and there snot any other place you can quickly get onto the fire line and shoot one of these guns except right here in Oklahoma."
Also at the event was a special raffle for a 19-66 custom made Ford Thunderbird.
It was built by Bill Fleming who recently lost his wife to colon cancer.
The proceeds from the raffle will help Fleming pay for his wife's medical bills.
"It was something that I did for my wife, she would've loved the car. I really hate to see the car go...it makes me sad, but Im glad to see a young man won it."
