Will this fit on a 20” rifle barrel? Expert Answer

Please email us at TechSales@OpticsPlanet.com with the make and model of your barrel so that we can verify the gas system length.

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

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.
