[QUOTE="CBH Australia, post: 2210969, member: 116486"] I reckon he cut a tenon then threaded it to 1/2"x28 then made the cap , and adaptor to go from 1/2"x28 to the required 5/8" thread of the brake/suppressor etc. There might be a cap for this, sometimes they are knurled. I reckon he had a nice tight thread, nipped up the new adaptor to the carbon fibre tenon with everything cut true and square, maybe the slightest concave leade on the back of the adaptor tenon to make it all seem seamless and completed the final machining of the crown after the cap(adaptor) was tightened on. In the images the seam seems seamless but it must be there as it's screwed onto the end of the barrel. Maybe he even had a larger diameter to start and machined that down to meet the C/f wrap after using a pipe wrench to tighten that cap hard. Then just turn down to suit taking the marks out. Unfortunately that is all above my skill set but I to tinker on an old school lathe. [/QUOTE]
