Our students learn Gunsmithing through the repair of customers’ firearms in the largest Gunsmithing shop in the United States. Our students perform 4,000 to 5,000 firearm repair operations every year. Our gun repair school is located just 10 minutes from Denver, CO and less than 90 minutes from Colorado Springs, CO. The gun shop offers firearm repair and gun modification services so students get a variety of real-world experience. Students must be 21 years of age to start a program, but there is no age minimum to apply to CST programs.
