What is On-The-Shelf?

All available Barrel options are displayed on a Shelf as Profiled, non-chambered barrels. When you place an order, we hand-select a barrel from our shelf and customize it through our production process. Think of it as a “Dealer’s Choice,” but each barrel is made specifically for you.

At MOS-Tek, we believe that skilled craftsmanship is the key to creating an exceptional barrel. Every team member is trained to uphold our core principles—precision and quality come first. We never compromise on quality for the sake of quantity; instead, we focus on a meticulous process that ensures each barrel is crafted with care and expertise.
