Modeled in Fusion 360 (M32x1.5) and printed them - they needed to be scaled up by 2.5% to account for slight inaccuracies in the 3d Printing process.
So I needed to remove the proprietary barrel nut for the stock G&G front end - so had to design/print a tool to do it:

(I know, I know, haters gonna hate - this is an exercise in curiosity more than anything else)
I intend to make a whole front-end using a ~40mm Carbon tube epoxied onto a 3D printed barrel nut, a printed outer barrel stub at the receiver end, a printed barrel stabiliser cap at the front, with the inner barrel free-floating in between.
