Hi everyone. This is my first post and within the year purchased my first gun. I apologize if this is addressed somewhere but I can't seem to find direction or recent posts. I seem to be having issues finding a reasonably priced upper receiver without an A2 flash hider. Then I started looking for a barrel with compensator without much luck. How does everyone purchase them? If I were to purchase a threaded barrel and compensator with existing guns, how do I not run afoul the many laws of NJ prior to pinning/silver solder it. My assumption is you ship it to a gunsmith to affix. Any advice would be appreciated. I think I am missing something the forest for the trees here.
