Nope, a .22 rimfire barrel has been in the works for some time now. I suspect what was shown on the TV show was one of the pre-production models. This .22 rimfire barrel will have an offset chamber/bore. As far as I know, at this time it will be a single run of 500 barrels for a single wholesaler (JSC). T/C may make it a production item, if they see a big enough market. Get your orders in quick, and wait - mine has been in for about 2 months.
