I have already ordered an extractor, buffer, sear, hammer and trigger from Volquortsen. After firing a friend's 10/22 with the bolt release and extended mag release, I am not interested in those mods.
Not sure about the Hogue stock. I don't have any issues with the one it came with, and Hogue hasn't started making them for the takedown version anyway.
I don't like the banana style magazines. I ordered the triple clip for the 10 round magazine.
