Finally, someone has come out with a great replacement barrel for the 10/22 takedown. This is the Tactical Solutions SB-X takedown barrel. Machined from 6061 T-6 aluminum, this is a lightweight yet super accurate upgrade for your rifle. It measures 16.5”, but the barrel itself is 12.375” with a permanently attached shroud to achieve the legal 16” length. The best part is that you get all the benefits of an SBR without doing all the paperwork! It also comes with an INERT/FAKE suppressor. Again, it is a FAKE suppressor. Threads are ½ x 28.
