RKellogg;
A couple of things about changing barrels on 10/22's. First, don't be too quick to do it. I've seen several stock 10/22 barrels give outstanding accuracy provided the owner did his homework with ammo testing. The second point to that qualification is that if your barrel isn't satisfactory, you can try another stock barrel for little or nothing. People who've taken theirs off for a .920" will frequently give their stock barrel away, or sell it very reasonably.
If you do do the swap, there are some other points to keep in mind. The quality of the barrel to receiver fit is a variable. Some are loose, some are slip-fit, some are tight. The important factor is to keep the barrel square to the bolt. A Doug Koenig V-block, available from Brownell's, can help with that. Check to see if the breech end of the barrel is square to the chamber. Also, watch how you tighten those allen head bolts. Don't tighten one fully & then tighten the other. Bring them down together & if you have it, use an inch-pound torque wrench.
I'm not talking hi-tech here, just use a good machinist's square to check the breech/chamber relationship. You don't have to have a torque wrench, just be even in tightening both bolts.
Warning!! If you get a Brownell's catalog & go to the 10/22 section, you'll be lost. Your life will change, and you will aquire more than one 10/22. But hoo-boy, will you have fun!
