Pushing her to start out on an AK is a huge mistake and you will likely turn her totally off guns for good like that. If you want to teach her to shoot, and she wants to learn, start her with something light and light recoiling. The AK can come later after she works her way up to that. It'll take time for her to build up the muscle strength to operate a heavy rifle anyway.
I would recommend one of the M&P15-22's. It's very light and obviously no recoil, plus it has that look to get her used to shooting that style rifle. There are several colors such as black, green, desert tan, pink camo, purple camo and probably some I can't remember. They are inexpensive, accurate and aren't ammo picky so it's a perfect choice for a first rifle. I grew up shooting but even I LOVE my M&P15-22! She's bound to love one of the color choices and she will love that you listened to her and bought her her first gun, especially since it's something she can shoot her entire life.
Don't push her to start on an AK unless you want to risk turning her off guns altogether.
This is mine, it's great for teaching new shooters or for experienced shooters too.
