As always great gun buying experience. The best shop in the greater area.
Great environment, knowledgeable staff and great inventory!
Literally one of my new happy places! It’s so amazing!
These guys are great! I’ve been shopping at Circle Star for years. If you want to work with down to earth and friendly guys with good prices, this is the place for you.
When it comes to customer service, Circle Star goes above and beyond. I have been investing in firearms, ammo, and equipment with this shop for years… and will continue to do so.
One of the best Firearm places I have been. Everyone is super nice and the owners rock. …
Great service, good atmosphere and the sales people are very professional. Good prices and selection as well. Worth the short drive out of town.
This is the best and most reasonable gun store I have ever been to. They are the nicest guys you will ever meet. … They will treat everyone the same whether you look like you could buy the store or barely afford a gun.
Give us a call
Talk to the guys at the store. We're open Monday to Saturday 9 AM to 6 PM and Sunday 10 AM to 5 PM.
