I have the Phase 5 Tactical one, and it does not fit. I was in hopes of not milling the upper, but that would fix it. Phase 5 lists one that looks simular, but is listed as to work with some side chargers. I've placed an inquiry if it works with the AA upper, but have not heard back. I might try making a lever before milling the upper.
