Anyone got a pic of the underside of an ARMS mount?

[Ricketts]

I bought one at a fun show yesterday and need to know if I have everything--

If you do, please let me know--I think mine is a #4 but I don't think it matters as to the underside. Maybe. I dunno--

The only difference is whether or not it has the spring guide rod. Both of them have a metal plate/tab on the rear that is riveted to the mount. If it doesn't have the tab it means someone didn't like it and bubbaed it off.

You can "convert" a #4 to a #3 by cutting off the rod.

Thanks Stranger. I guess I have a 3 because I do have the tab but not the rod.

That's what I was looking to find out.

RobMac here on the files has converted some of his ARMS #3's into #4's by silver soldering a piece of drill rod onto the tab to act as a spring guide. From what I have seen of them, they work pretty good. Maybe he can fill in the questions as how and what size, etc.
