I just ordered a new mid length gas tube because I messed up my last one by being stupid. Now that the new one is here it is too long, so my question is how long is a mid length gas tube? the one that came in the mail is 11 3/4"
here is what I found from cheaper than dirt is this right?
There are four main lengths of AR-15 gas systems in use today: Pistol, Carbine, Mid, and Rifle. Each one of these gas systems require different length gas tubes and handguards, so it is important to know which one you have before ordering parts for your AR-15. If you dont know what size rifle you have, it is fairly easy to determine by simply measuring the length of your handguards or gas tube.
Pistol-Length
The pistol-length gas system is used almost exclusively on AR-15 pistols or AR-15 rifles that have very short barrels, usually 10″ in length or less. These systems generally have a gas tube of approximately 4.5. The handguards or free-float tubes for these systems are generally between 3-4 in length. Some people are now installing low-profile gas blocks and carbine length free-float handguards so that they can have a longer and more comfortable forearm grip area.
Carbine-Length
The carbine-length gas system, combined with barrel lengths from approximately 10-18, is perhaps one of the most common setups across all types of AR-15 rifles. Carbine gas tubes are approximately 7.5 long, which means that the handguards will be approximately 6.5-7 long, such as the Mako Handguard and Rails System, the Daniel Defense Omega Quad Rail, and the Midwest Industries Carbine Forearm.
Mid-Length
Mid-length gas systems have become quite popular, and are most commonly used with barrels from 14-20 in length. They give the shooter a longer sight radius and reduce some of the wear and tear on the upper receiver. Mid-length gas tubes are approximately 9.5 and require a handguard around 8.5-9 in length. Choices for handguards of this length include the UTG Free-Float Mid-Length Quad-Rail and the UTG 2-Piece Quad-Rails.
Rifle-Length
Rifle-length gas tubes are generally about 13 long, requiring handguards ranging from 11.5-12 long. These are usually found on rifles with barrels 20 in length and longer. If youre looking for replacement handguards for a rifle-length system, check out the UTG Free-Float Rifle Quad-Rail, the UTG 2-Piece Quad-Rails, the AR Carbon Fiber Free-Float Tube, and the Yankee Hill 2-Piece Quad-Rail
