the Axis is a good rifle, but i will throw in my suggestion, the Marlin X7 series of rifles. they even have them in youth models that might fit your wife better because of LOP. they are very accurate, very well built and the fit an finish are excellent. priced very decently also.
personally, i have shot several different Axis rifles over the past couple of years, and honestly, they are a good rifle with decent accuracy. but i like the Marlin X7's a liitle better. that's just my personal preference. for me, i like how the Marlin fits me better than the Axis. choosing the Axis would still be a good choice though.
