KAK Industry AR-15 Mid-Length Gas Tube Silver

The KAK Industries AR-15 Mid-Length Gas Tube routes propellant gas from the gas block back to the bolt carrier group to cycle the action. It is sized for a mid-length AR-15 gas system, which places the gas port between the carbine and rifle-length positions.

The tube has a silver finish that helps builders tell gas system lengths apart when working on several uppers at once. A properly sized and finished tube matters for reliable cycling, since a bent, undersized or poorly finished tube can cause short-stroking or gas leaks.

The tube is intended for standard AR-15 mid-length gas systems and suits a new upper build or the replacement of a damaged tube. A roll pin is not included, so have one on hand to secure the tube to the gas block during installation.
