MSP - There are quite a few conversions done over at RFC and they all said it is really easy - just swap out the barrel and the bolt handle, for the most part. For your regular stock, you would simply need to get one in a Sporter barrel configuration (vs. a 0.920 bull) - I have seen the basic barrel/bolt handle combos for as little as $145. I have been real tempted to do this with the one 10/22 that I have... but haven't been able to justify it yet (as I already have 3 bolt HM2s and they fill any need that I really have).
