Yes, I cut my daughter's stock a couple years ago to fit her. I actually had to cut it a couple times, but I saved the drop off's. You can just install a new sling stud, limbsaver slip on pad, and you're done. I've epoxied one of the sections back on already as she's grown. Doesn't look the prettiest, but it's a $199 gun and nobody but me and her sees it, and now it fits her. I was hesitant at first, but it's a $199 gun, so even if she got 1-2 years out of it, throw it away and get another one. I have 2, I bought myself one when I bought my daughter's, so I figured I'd chop hers til it fit, and once she outgrows it I'll just give her mine.
If you did for some reason care about the looks, cut the stock, shape a 1/8"- 1/4" thick piece of wood to match the new size of the back of the stock and screw it on, then get a grind-to-fit limbsaver recoil pad. Lastly, screw in a new sling stud and your all set.
