kmc0929 Posted February 9, 2010 Share Posted February 9, 2010 So a friend from Beretta/Benelli said they could get me a collapsable stock. How can I tell if my m4 will accept one? Is there a part that goes over the recoil tube and has the notches or does my tube have notches on it? Let me know! Quote Link to comment Share on other sites More sharing options...
