10/22 receiver and action differences.

[HogBob]

Can anyone tell me what are the differences (if any) between the receivers and actions Ruger installs in their 10/22 carbines vs. the receivers and actions in their 10/22 bull barrel Target model? Since the Target trigger pull is lighter than the stock Carbine, I am curious what the other internal mods may be. My rifle is a 1986 carbine that had its "lawyer trigger" smoothed by a gunsmith and I have since installed a Ruger hammer forged stiainless target barrel, Rimfire Technologies V Block Barrel Stabilizer and Machined Screw Combo,, extended magazine release and a Boyds laminated pistol grip stock. It shoots well (probably better than I do) and looks good but I wonder if its as good as the Target from the factory.Any info and/or opinions would be appreciated.
