Hey guys just to start off I am quite a newbie in the airsoft game and am more looking to do my first custom build. I am an engineer by trade so have access to a lot of machinery such as a CNC to do certain parts that will be totally unique but I will get to that eventually.
My issue is that i have got myself a CM16 raider as a building block to start from and am looking to extend the barrel from 6.5" to 15" in length. The installation of the barrel and hop up is of no concern but what i cannot find information on is the black sleeve that covers the inner barrel in which the external end barrel attaches to. (i will include image showing this part in question)
Im stumped as to finding any longer barrel 'sleeve' for want of a better word, and am under the impression i would need one to attach an external end to the gun.
Any help would be greatly appreciated and i can take more images if needed.
