I have a AR10 with a Stainless barrel and it came with a basic black AR flash hider and I wanted something in stainless.
I decided to make my own as a learning experience and it saved money ..... if I don't count my labor time involved
A couple things I did for the first time on this was I made my own boring bar the cut internal threads rather than buying one and I cut internal threads for the first time.
Here is what I started out with.
I bought 2' of 1" Stainless bar stock.
I cut off a chunk and and drilled my bullet bore .020 over .308 so a .328 bullet bore and I drilled for the threaded end. just undersized in order to cut a 5/8x24 thread. Once I had both ends of the soon to be brake drilled I needed a tool to thread the inside with.
I wanted to thread before any serious work since there was a risk I would mess up and have to start over.
I made this tool to thread with:
I cut the threads going slowly and yay it went worked first attempt
I did not take any pictures milling the ports I forgot but once I got the port milled I had to trim material off the threaded end to get the port to index properly.
Once that was done I contoured the outside down.
As you can see it is starting to take shape I missed a few pics along the way.
Finished product.
I tried real hard to perfectly match the barrel OD but could not get it just right so you can still see a small line. the only way I think I could do that would be to have the brake on the barrel for final finishing
