CDS ARMS was born as the result of a lifelong passion for firearms and shooting sports. We saw a noticeable void in the customer service and knowledge offered by the big box stores and ‘old school’ gun shops, so we decided it was time to take action. Despite political & market uncertainty, extensive paperwork, complicated & expensive licensing and other barriers of entry, CDS ARMS, LLC was founded in 2011 by Cory Sementuh. Since then we have continued to grow serving thousands of happy and satisfied customers. When you contact CDS ARMS you will receive a personal, knowledgeable reply, not a script from some worker in a call center on the other side of the globe.

Our mission is simple: To provide the best products and service to our customers at the fairest prices possible. We take great pride in our company, our commitment to customer service and in the products we sell. We strive to provide competitive prices with honest and quality service.

Buying a firearm doesn’t have to be an intimidating and difficult process; we can help! The NFA ‘Class 3’ process seems like a daunting task but we make it easy! For the inexperienced or new shooter, we relieve the stress and cut through the BS. For the experienced shooter or collector, we offer the know-how to get the unique products you need.

No matter if you are doing a $25 transfer or buying $10,000+ in products, we will treat you the same and see you through the sale from beginning to the end.

We want customers to say they were happy to do business with CDS ARMS and refer us to their family and friends.
