For that kind of money, you can hardly go wrong (if the reading says it's OK) (it's all plastic)
I prefer a straight, clear, light 4X (non variable) scope on my .22 rifles. If you want one, look for the appropriate available scope mounts for that rifle. Keep it all lightweight.
How much are extra mags? (I'd want at least 3-4)
An AR take-down is probably easier to clean than most std .22's (and from the breach, not the bbl)
If it takes aftermarket grips, I highly recommend this Ergo grip. Even with my small hands, standard (cheapo) AR grips have my trigger finger going clear through the guard to my knuckles, and I have to work at only using my finger pad. For small money, this makes a big difference, and your trigger finger isn't all the way through the guard. (I use the right hand grip, not an ambi)

Only 40 miles away, this is a
much nicer rifle (for $89 more, but will require an optic).
