I have just received a PreBan Colt AR15 Match HBar & I need to know how to break it down into 2 groups by extracting the front & rear pivot pins. The rear pin is easy, it just pushes out, but the front one has a slotted screw head in either side and it turns when it is turned on either end. I have tried holding one end & turning the other but I can't hold the one & turn the other maybe my screwdrivers are too small or maybe I am doing it wrong.
Can somebody explain what I should be doing?
