Gas system measurements (the distance between your upper receiver and your current gas block) are as follows:

Pistol 4.3"

Carbine 7.3"

Midlength 9.3"

Rifle 12.65"

**Note: Intermediate-length Gas Tubes have recently been added to our options. There are several versions of intermediate gas systems on the market. The Intermediate Gas Tubes we offer measure 13.65" from tip to tip. This is not the receiver-to-gas-block measurement we reference above and on the "Choose Your Gas Control" page. Please verify the version of Intermediate gas system your carbine uses. If you need a different version than what we offer, White Oak Armament makes straight gas tubes in custom lengths for a reasonable price.
