We wanted to do an AE stock, it's a nice action. Unfortunately with how the trigger is set up, it just won't work in our chassis. It is a round action so is different footprint than a M2008 as noted above. Honestly the only reason I can think of right now to get an AE over the Badger M2013 action would be the shroud mounted safety on the AE gen 3 which I personally like better than the Rem safety for some strange reason. If you get the Badger then you will have a whole host of stock options.
