I was under the impression the GM sporters need a little bit of inletting near the receiver.
Dunno what happens when CPC sets back and rechambers a standard 10/22 bbl (as far as bbl to stock gap).
Rimfire Sports is out of the blued 20" GM sporters.
I too am wanting a light hunter 10/22, w a fingergroove stock.
GM sporters do require the barrel channel to be opened up just forward of the receiver.
CPC doesn't set the barrel back very far, 0.187" to 0.250" according to their site, so there shouldn't be any need to do any inletting. Randy will do the absolute minimal set back if he knows that the barrel is going back into a mannlicher-style stock, so that the barrel will still extend beyond the stock's end cap.
I've had CPC do their full tune-up on three 10/22s, twice with GM sporter barrels and a mannlicher with the factory barrel. I think that a CPC full tune-up is a better value for most people than just swapping out after-market parts. Randy's full tune-up is a holistic approach, in that he reworks the rifle so that all of the parts fit and work together in harmony.
