Our Story

   Mommsen Sport & Auto was founded in 2004 by life long outdoorsman and hunting enthusiast, Larry Mommsen. His daughter, Brianna, has since joined him in the shop. 


We pride ourselves on our top-notch, professional service, high quality products, and fair prices. Mommsen Sport is your one stop shop for your next firearm purchase.   

We deal in nearly every brand of  firearm and shooting related products. We keep around 100 firearms in stock and have a constant flow of new and used firearms coming in daily.  


We buy, sell, and trade new and used firearms. 


We also sell a variety of suppressors, optics, ammunition, cleaning supplies, holsters & cases, accessories, & targets. 


You are sure to find just what you are looking for to make your next hunt or sport shoot successful. If we don't have what you're looking for we can try to get it.
