I got my tax stamp back for my Sig 556. I planned on sending it to a gunsmith but a few local smiths did not seem interested in doing the job for me. So I figured I could tackle it on my own.
This poor Sig was an ugly duckling. What I really wanted was a SG553 clone.
I did the first cut a little long and did some practice threading on the cut piece of barrel. Left enough room to send it to a smith if all went wrong
After some practice, I decided to go ahead with the job on my own. Cut it to 10 inches.
Used a 90 degree facer to get the barrel cut straight.
I used an annular cutter to turn the barrel down enough to accept the 1/2x28 die. This part took the longest.
Then threaded it using a thread alignment tool and die from cnc warrior
Crowned using an 11 degree cutter from Brownells
Muzzle device fits perfectly
Very happy with the results
