I bought a Moe+ grip for my 15-22 and learned that the maid grip wedge won't work with it so instead of wasting time returning it ill pass it on this coming Friday the 19th before I go to work. So getting your "in's" before Thursday night and remember it only works with the maid and moe grips!
Please add me in on the generous karma. I've been meaning to swap the grip on the 15-22 to a MIAD just like on my 6720, and this would give me the motivation to do so. Thanks for the chance!
