This may be a obvious question but I must ask it anyway. I have just ordered a new M4 and was wondering if someone could tell me if this stock will fit my M4? Also will it be fully retractable on the current model M4 that I have ordered? http://www.benelliusa.com/shotguns/benelli_m4.php Thank you for your help.

Hi, I am interested in buying one of these but I just need to know if they will work on the current model M4 that I have ordered? http://www.benelliusa.com/shotguns/benelli_m4.php Sorry if this is a noobie question but I just need to make sure. Thank you for your help.
