I have a standard 16" barrel and would like to go a little shorter, ideally a 10.5 or 12.5. I know you need pay a tax/fee and get some paperwork for these, but my question is, what is the shortest barrel you can get on these rifles without the tax/fee and paperwork?
I know in california you can get a 14.5" barrel if you weld the flash hider on, but I haven't been able to find much about minimum barrel lengths in co.
Any other personal advice would be appreciated too. I know going shorter messes some things up, need different buffer springs, etc. Can you get away with all the regular components if only going to a 12.5"?
Thanks for the help!
