Description
This custom barrel bands hold the barrel in perfect alignment with the carbon fiber air tank on the FX M3 or FX M4. These are 3D printed from 100% fill with PLA+, and are very rigid and tough. There is a small set screw in the top of the band that should be tighten slightly with the supplied hex wrench. The set screw has a nylon tip so that it does not scar the shroud.
