All of us want something different for a specific build we have in mind. The Barrel builder Web app allows you to pick and choose what components you want to include on your built-to-order barrel assembly and none of the ones you don’t. This can save you time, headache, and money when forced to remove parts you don’t want from a cookie cutter pre-built barrel assembly. The barrel builder also give you a visual representation of what your assembly will look like. Please choose your desired gas system length and click the “build your own” button to enter the barrel builder.
