If a 10/22 or a Marlin 60 can run with an aluminum receiver (AND be made in takedown versions), they SHOULD be able to make a sa-22 that does as well. That, and a lightweight barrel (steel liner/aluminum shrouded, with enough steel in the shank to attach that cantilever scope mount adequately), along with a LIGHTWEIGHT synthetic stock, would have been something.

I’m not sure WHAT a heavy bull barrel, adds to this package.
