Hello. I have 1/2x28 threads on my 5/8 stainless barrel Mini 30 with a 1/2x28 to 5/8x24 adapter connecting a 1" diameter muzzle brake which has 5/8x24 threads. The setup works great, but the step down from brake to adapter to barrel doesnt look that great. What I would like to do is have an adapter made from 1/2x28 to 5/8x24 with a 1" round diameter with atleast an inch of meat to have a gradual slope milled between the barrel and brake. Does anyone know a manufacturer who would be capable of making this or do I need to make up a diagram to be understood?
