Brownells shows an inside tube for the Winchester 90 in WRF, which should be good for the Remington .22 special as well. It is 20" long but of course can be cut. The stock number is 895-699-000AC. You can go to their web site and check if they still have them. Cost in my catalog is $25 plus s&h, but they may have gone up. Check www.brownells.com
for more info.
If they have it, you can order it and return it if not right as long as you don't mess with it.
