Like most guys have been saying...lots of options.
Don't the stock? Blackhawk AXIOM for $75
Don't like the sights? Comes drilled and tapped, plus comes with a rail to put on the top of the receiver for red dot, scope, etc...
Trigger? Lots of options
Trigger assemblies? Lots
I think I've made my point. Plus lots of parts and expertise out there for the 10/22
