AEG/HPA Carbon Fiber Outer Barrel for AEG/HPA with anodized aircraft aluminum parts

What’s a Carbon Fiber Outer Barrel? Can I buy it and is usefull for my Airsoft build?

Carbon Fiber Outer Barrel and Glossy Fiber Outer Barrels are two components for the front part of the Airsoft Rifle.

The Product is composed from a carbon fiber pipe with a front threaded insert in M14x1LH, made out of Anticorodal 6082T6 aluminum alloy and the pipe. The design of the frontal threaded insert grant the perfect alignement of the inner barrel; The back part, where the hop up chamber goes, is an aircraft alluminum insert that grant solid assembly n the upper receiver and is aligned thanks to 3 titanium made grain.

All the aluminum parts are anodized in different colors.

To grant the perfect alignement of the Inner Barrel, as mentioned there is a ring, made out of Delrin (POM, high slip plastic material) and have a internal diameter of 8,60mm with a tight tollerances of -0 / +0,05mm.
The nut is specifically realized with the two guides for the Hop up chamber in the measurement of 2,45mm +/-0,05mm allowing you to get a very good alignement of the hop up chamber. It is possible to be needed to file it a bit in case you use a plastic hop up chamber avoiding wobbling movements.

The Inner Barrel lenght must be enough to reach the alignement diameter of the front threaded insert or the alignement can’t be granted.

The alignement grains are three and are custom made under my design having an head of 3,20mm +0/-0,05 mm of tollerance, granting a very good alignement without having issues from a too much gap between the grains and the upper receiver guides.

The weight can vary from a minimum of 45g based on the lenght.
