Nordic Components Mil-Spec 6-Position Buffer Tube - Black Finish (15-BFRTUBE)

The Nordic Components Mil-Spec 6-position buffer tube is a no-frills, American-made replacement tube for AR-15 builds that demand simplicity and reliability. Built from 7075 aluminum with a black anodized finish, this tube alone—without the endplate or castle nut—gives you the core component you need when you're assembling a lightweight rifle, updating an existing platform, or customizing your AR platform without unnecessary extras. Nordic Components manufactures this tube stateside, giving builders a domestic alternative that bypasses the overhead of bundled components you might not need.

A Mil-Spec buffer tube works with standard Mil-Spec stocks and provides six positions of adjustment for cheek weld and length of pull, making it adaptable to different shooters and gear configurations. The tube itself is straightforward: solid aluminum construction designed for consistent performance whether you're setting up a bench gun, a varmint rifle, or any AR variant where you want to control exactly which parts go into your build. Weighing in at 0.3 lbs, it's lightweight and won't add unnecessary mass to your system.

If you're a builder who already owns surplus or aftermarket endplates and castle nuts, or you're replacing a worn tube in an existing rifle, this component-focused approach saves money and lets you specify every detail of your final product. Nordic's domestic manufacturing means consistent quality without the markup of integrated kits or drop-in assemblies.
