Rifle length gas tubes are roughly 12" in length from the receiver. Depending on how you came to your measurement, it may or may not be what you need. Gas tubes are dependent on the gas system of the barrel: rifle, mid-length, carbine, or pistol length. Email us at techsales@opticsplanet.com and let us know the exact barrel you have, that way we can confirm the correct length gas tube for your barrel.
