Hey, sorry that I'm reviving an old post but I'm very interested in this stock (AGMF 500 FK SB) and it's listed as one of the stocks that you have reviewed but I can't seem to find the review information under this thread. Any advise? I'm interested in this one, or the MESA Tactical M4 LEO telescoping stock with Recoil Reduction tube http://www.nokick.com/Mesa_Tactical_LEO_Recoil_Stock_Kit_for_Mossberg_p/mesa tactical 93220.htm have you compared to two of them against each other?
