10/22 Coversion
I was reading your Post, Changing a 10/22 barrel and adding a new stock, and the likes are relatively easy procedures. The barrel simply comes out of the bore (look at your owners manual to breakdown your gun), then just put everything, New Barrel, stock, grips, ect back on when putting it back together.
You can make your 10.22 into a 2 round burst or full auto with a relatively easy conversion as well. I am a certified Master Gunsmith, Reloader, and FFL holder, and making the 10/22 into a selector or full auto takes a little coversion, but it is fun since 22 ammo is so cheap. One of the areas I specialize in is making tactical conversions for Semi-Auto Rifles (SKS, AK, AR-15, 10/22, Min-30, Mini-14
BTW, You can do a similar conversion on Mini-14's and Mini-30's.
Let me know how it goes. Remember, You will have to Re-Site your 10/22 when you are finished (this involves making sure the barrel is straight on its axis for front site and adjusting the back sights for accuracy! I suggest having a Gunsmith do this. Bore sighting to 100 yards is a relatively simple procedure (if you know how to do it), but don't just start adjusting sigts or you may end up with broken sights or a very innaccurate rifle, since I get Guns all the time where people are using household scredrivers on their guns for sight, or other adjustment and end up marring or stipping the heads on the screws. That is why we have Gunsmithing ScrewDrivers, and Tools that protect against this.
