Yeah, I'll probably just order a 10/22 then. Been wanting one for tinkering with.
Hell, shotguns are cheap too. May just get a Ruger 10/22 and a shotgun at the same time if I can do so for less than $500 (should be doable). Need to see what the local shop has.
I see two contradictory impulses here:
1. Tinkering with the Ruger 10/22. This will COST you money. By the time I was halfway done, I think I've put in more than $600 in parts & tools.
2. Getting cheap, affordable guns. You cannot do both this and the above.
If I could start all over, I'd get the Marlin, which is more accurate than the stock 10/22, rather than improving the 10/22. The savings will pay for some Appleseed shoots. Use the Marlin to train & get good. Then if I want a really nice .22LR rifle, I'd save up and buy one of those guns that cost in the four-digit.
Then I'd get a used, simple Mossberg 500 (bead sight, no extension tube, nothing tacticool). Those things will take a beating, and most people don't shoot their guns a whole lot. So you can find a cheap one in a pretty good condition. It just costs too much to get a properly fitted defensive shotgun, and unless that's your primary defense tool, you won't have much use for it at the range. When other people are happily shooting trap or skeet, your 18" barrel and ghost ring sights will get in the way.
But, hey, it's your money! Does the Dude abide?
