The Remington tube matches the Express I put it on. Keep in mind the Remington kit comes with a much better clamp than you'll get with a Tac Star or Choate. That makes them a little more valuable IMO.
I see alot of Nordic tubes at 3 gun matches. The look to be very well made and have a teflon coated aluminum follower. If I buy another, thats what it will be.
