I put an ATI Akita adjustable hunting stock on mine. It adjusts from 12 3/8" out to 14 3/8", has a great recoil pad and the set includes a matching forearm. I like it because it looks like a traditional hunting stock but adjusts to fit most people or when you hunt with lots of clothing or just a "T" shirt.
You can also keep that factory stock and reinstall it if you ever want to trade that gun.
Thanks,
Clark
