I have a non-restricted CZ-858 with 18" barrel.
Am thinking of bobbing about 5" off the barrel and installing a brake.
First question: Can I do this and change registration to restricted?
Second: Since I have to cut the threads on the barrel, would it make any difference if I used a 14x1 thread or a 9/16" thread. The brake I am looking at is available in both threads and both appear to be similar in size, just a bit more than a half inch.
