The heavy barrel 10/22's shoot so much better than the factory skinny tubes. If you want an accurate 10/22, you have to go with a target tube.
I've had two target barrels on my 10/22. First was a low dollar one, I believe it was a green mountain. Accuracy wasn't nearly what I expected, and lots of ammo would fail to fire due to not fully seating in the chamber. The barrel was sent back to Brownells, and I ordered a Clark ss. I'd wanted the shorter barrel, but all they had in stock was the 21" tube. With the right ammo and me doing my part the gun will shot 1/2" 10 shot groups at 50 yds. Also the Clark functions very reliably with both target ammo and bulk plinker ammo. I will be cutting the tube to 16 1/2" to make it handier, and am thinking I'll fit the stub to a MKII pistol.
The upside of 10/22's is no special tools are required nor skills, so don't be afeared to swap parts. It seems like the sporting goods stores often have 10/22's on special, and you can get a couple bucks for the factory stock and barrel. I'd say that route is dollars ahead of the factory target model, with perhaps a higher quality barrel.
