Question reguarding the Magpul Mbus sights.
Hey fellas I tried uploading some pictures to give you guys a reference but I'll just give it my best shot at describing it. I picked up a magpul rear sight and was wondering do you attach this sight to the farthest back rail slot on a flat top? Or should it be on the second to last slot. If it is on the back slot then it over hangs the end of the receiver a little bit and is flush with the back of the charging handle.
PS. do these sights make good dedicated rear sights? I haven't got the money for a good optic yet and I was thinking about picking up a cheap carry handle if this isn't the way to go.
