I love my Ruger 10/22. It's not exactly the first Ruger I've owned but like the others I have, it's a great firearm. The ONLY failures to function I had with mine was with an aftermarket magazine, which I promptly returned and did what I should have done all along - bought a Ruger BX-25 mag. LIke Blackbeard above, I did the M1 Carbine replica thing and I completely agree with him, if you're gonna do it, do it all the way. I got the sling and oiler and the sights.
The scary part is how accurate those sights actually are. Last time we were at the range, some friends and I put paintballs on golf tees and I was able to easily do some painting and shoot each ball off the tees at 20 yards with open sights. There were people there that couldn't do that scoped. For those out there that don't know, paintballs are .68 caliber so those are tough little targets out past 50 feet, but it was a great challenge and my 10/22 was MORE than up to it.
Great rifle for ANYONE to own. So many options for upgrades and personalization mated to reliability and simplicity, from a proven name. You can't go wrong!
