In researching my white mountain carbine, I was able to get my hands on the catalog from the first year it was produced, 1989. The listing confirmed that those inaugural models did, in fact, have a 1:20 twist rate. If anyone is interested in seeing the listing (as well as the listings for the Renegades of that year, drop me a PM and I'll send you a PDF of the pages.
