thomjb Posted November 9, 2010 Share Posted November 9, 2010 What size wrench is needed to remove the front sight on a M4? I am assuming metric and around 5mm? Any help appreciated. Thanks in advance Quote Link to comment Share on other sites More sharing options...
KB Fab Posted November 9, 2010 Share Posted November 9, 2010 5.5 millimeter. Quote Link to comment Share on other sites More sharing options...
heckler&kochp2000 Posted November 9, 2010 Share Posted November 9, 2010 5.5 it rounds out the edges pretty easy on the nut but it will fit. i use a screw driver kit that looks like it can be bought at Harbor freight or like a 99 cent store that come in those little 5 pack plastic square containers that those little screw drivers come in.
