White Label Armory Carbine Buffer Tube Features The White Label Armory Carbine Buffer Tube is machined from aluminum and finished with a hardcoat anodized coating giving it the durability to withstand the repeated cycling of the buffer and spring inside it. Built with six positions the tube allows a stock to be adjusted across a range of lengths of pull letting a shooter dial in the fit that works best for their body type and shooting style. Designed specifically for standard AR-15 lower receivers the tube threads directly into a mil-spec receiver extension without requiring any special fitting. Finished in black the tube matches the vast majority of AR-15 builds without standing out. Compatibility with mil-spec stocks and braces means this buffer tube works with a wide range of aftermarket furniture already on the market giving builders flexibility in finishing their rifle or pistol. At just 3.8 ounces the tube adds minimal weight to the rear of the rifle while still providing the full-length housing needed for the buffer and spring assembly. A quality buffer tube is a foundational component of any AR build since it directly affects how the stock mounts and adjusts on the receiver. For AR-15 builders working with standard lower receivers the White Label Armory Carbine Buffer Tube offers a dependable mil-spec compatible option.
