KAK Industry AR-15 Gas Tube Features The KAK Industry Gas Tube is built to rifle length specifications directing propellant gas from the barrel s gas port back to the bolt carrier group to cycle the action on an AR-15 rifle. Proper gas tube length and dimensions are critical to reliable cycling and this tube is manufactured to fit rifle length gas systems without modification. Its Silver finish matches the look of many factory and aftermarket AR-15 upper components giving builders a clean consistent appearance. As a company founded to fill a gap in the market for quality American made AR components KAK Industry built this gas tube to the same standard as the rest of its parts catalog. Installing a gas tube is a common task during an AR-15 build or when replacing a damaged or bent tube on an existing rifle and this component is sized specifically for that rifle length application. Note that a roll pin is not included and must be sourced separately to complete the installation. Choosing a dedicated correctly sized gas tube rather than a generic part helps ensure consistent gas flow and reliable cycling across a range of ammunition. The KAK Industry Gas Tube is for sale at GrabAGun for builders who want an affordable properly sized rifle length gas tube for their AR-15 project.
