We used both the .223 it is bored for and the alternate chamber that will fire the .22LR.

I had no idea one could do that. It would be totally cool to do cheap target practice with the 22LR and then load with .223 with no loss of applicable muscle memory. How much does the optional hardware cost? What about magazines? What is involved in making the switch?
