Hi all. I currently have a CA compliant 15-22 (no threaded barrel), that I purchased early last year. I have since relocated to AZ, and I am thinking I would like to have a threaded barrel model. Is it better for me to get a new threaded barrel (if even possible), and swap out the barrel, or should I just sell the rifle I have, and buy a model WITH the threaded barrel? What says the 15-22 brain trust?
