Center pin issue with russian 91%

[mrmack00]

Anyone familiar with the Russian 91%?The bottom center pin won't make contact. It is connected to the positive block and has to be tightened; otherwise the whole positive block slides around, causing shorts. I tighten it just enough to secure the positive block. But that just causes the bottom center pin to be recessed too deeply and and it no longer makes contact with the provari... Any ideas?

Is this a clone or is it a real 91%
The real 91% has an adjustable center pin.

You need to take the 510 screw out and tighten the inside screw to the block, then put the 510 screw back in.
a common problem with R91's at first use.

Good Luck!

This break down shows the adjustable center pin.
