I'm trying to determine if the Oprod I have is for the "A" kit or the later "B" kit.
In a perfect world one of you gents will have both rods and we can document the difference. But if someone could kindly take a couple of pics of each side of the early "A" Kit / AC556 kit I would very much appreciate it.
Also - there are three aluminum parts in the kit. the longest and shortest are addressed in the instructions. However, there is another piece, about 1/2" long with a hole the diameter of the guide rod drilled halfway through on the long axis - and a larger hole drilled all the way through perpendicular to the long axis. What in the heck is this part for?
