Welcome to the addiction, it ain't a hobby, it's a financial commitment, but it is one helluva good time. That 10/22 isn't a rifle, it's a Lego set for grown-ups.
Let me tell you a little story, when I got my first one, I was the same way. I took it out, plinked for an hour, and came home going, "This is great, but... I could make it greater." I started fantasizing about carbon-fiber barrels and fancy stocks, but I made one simple mistake: I didn't touch the trigger...I'm out on a Saturday morning, plinking steel at about 50 yards, and I'm pulling this heavy, gritty thing. It felt like I was dragging a rusty lawnmower chain through a box of gravel! I was like, "Crap, I gotta concentrate so hard just to keep it steady while I'm muscling this thing." I realized all the fancy accuracy in the world is useless if you're jerking the shot because the trigger pull feels like it weighs ten pounds.
Forget the tactical stock or the scope for now. The very first thing you gotta do, and I mean today, before you buy anything else, is get a trigger upgrade. Drop-in kits are everywhere, or you can get a replacement hammer and sear for cheap. You will transform that rifle from "fun" to "surgical." When you pull that light, crisp trigger the first time, you’ll look back at that factory pull and laugh. It’s like putting a Ferrari engine in a golf cart. You'll thank me later...seriously, do the trigger first
