KAK Carbine Length Gas Tube

The KAK Industry carbine-length gas tube carries propellant gas from the barrel port back to the bolt carrier group, the essential link that cycles a direct-impingement AR-15’s action shot after shot. KAK Industry was founded in 2011 by Kurt Kosman specifically to close a gap in the market for quality, American-made AR-15 components at affordable, sustainable prices, and this gas tube reflects that same mission. It’s built to standard mil-spec carbine-length dimensions, securing in the gas block with a common roll pin just like a factory tube. Builders assembling a carbine-length upper from scratch, or replacing a bent or worn factory tube, both need this exact part.
