Q
Seam Currie, member, from PA, United States, asked on February 06, 2021

Will this fit on a 20” rifle barrel?

Expert Answer
A
Answered by Nick B., Gear Expert, from IL, United States, on September 17, 2021

That will depend on the the gas system length of your barrel, there is not a standard gas system length for a 20" barrel, though usually it will be a rifle length gas system in which case this gas tube would not be compatible. Please email us at TechSales@OpticsPlanet.com with the make and model of your barrel so that we can verify the gas system length.

Q
Jeremy, member, from CA, United States, asked on March 11, 2025

11” ar barrel what size gas tube would I use??

Manufacturer Answer
A
Answered by Faxon Firearms, Manufacturer from OH, United States, on March 26, 2025

This will depend heavily on the specific barrel you have. Most 11" or 11.5" 5.56 barrels use a carbine length gas tube, however, we do have an 11.5" barrel that uses a mid-length gas tube. If your barrel is a different caliber like .300BLK it may have a pistol length gas system. You will need to verify what length gas system your barrel is set up for and purchase the corresponding length of gas tube.
