An American Tradition

The right to keep and bear arms is a fundamental part of America’s freedoms, and that includes the ability to build, fix, and customize your own firearms for personal use. We provide the gun parts that let you carry on this tradition in the comfort of your own home, garage, or workshop without compromising on quality or breaking the bank. Our gun parts are completely legal under federal law and don’t require a background check to ship directly to your front door. While some states may have laws that limit the types or quantities of gun accessories and parts you’re permitted to own, we work hard to make sure you have access to the top legal parts you need that keep you hitting the mark at the range. We try to let you know when a part isn’t available in your area, but always make sure you know your local firearms laws for your own protection.

We do more than just sell the parts and accessories you need for your firearms. We’re also active in the national Second Amendment community, working hard to protect your rights to legal firearms and shooting supplies.
