I am having issues with removing the FCG from the gun. I talked to some friends who completed this process but it was a while back and couldnt remember how exactly they did it. All the videos i see on the net are for the 7.62x39 which requires two rivets to be drilled out. the 308 is a little different and it has some pins that seem to have a larger diameter on both sides of the left side opening and I was wondering if someone can shed some light on how to do this without ruining my gun. Ive attached two pics to show what i am talking about. Can anyone help??
