100mm 14mm+ External Airsoft Barrel Extension

Align your muzzle devices perfectly to the airsoft inner barrel with our custom length, lightweight extensions. Our external barrel extensions are available at 1mm increments, allowing you to mount your muzzle device at a precise length.

This lightweight external barrel can help you reduce the weight of your airsoft gun. It is made out of strong and resilient nylon polymer. Replace your removable heavy, metal steel barrel extension with Airsoft3D lightweight barrel extension. Our light-weight extensions are available in various colors.

We build custom barrel extensions to desired length. We can design a barrel extension to an exact length. Contact us with what you need.
