RFQ muzzle brake

[cm92]

I am looking to have a muzzle break made. I dont know much about machining so there may be some flaws, but this is what i was able to come out with. the only real tolorances are the threads and the bore. The bore can be bigger than what is labeled in there but no smaller. This is not in the design but i would like a small nut made to cover the the exteranal threads. I would like the out side of the knurled. Also please make note that the internal threads are left had thread. I would like out of some kinda stainless steel. and if possible power coated or anodized black.

What's the overall size of this part and thread specs?
