The Johnson County Sheriff's Office is getting some new guns at no cost.
Each deputy will get a new M-16 rifle.
The guns were free to the department through a government program that issues surplus military equipment to local law enforcement agencies.
Officials say the new weapons will give the officers an advantage when they work by themselves.
"They will have a better range and capability. They hold more rounds, and it puts the deputies on a little more even playing field with a lot of the public that's armed," said Chief Deputy Kevin Pelphrey.
The program also issues things like vehicles and uniforms to local agencies that need them.
