Fox CS mkIV roll pin

Postby bridant » Thu Oct 16, 2014 9:22 am

I have a conrod for the MKIV Combat, label on the package says "M6040 roll pin". There are two small black pins included in the pckg, I cannot see what application these would have using this conrod! Anyone have any ideas?

This roll pin goes through the piston at the wrist pin. There should be a hole through the piston skirt that lines up with the same hole in the wrist pin to retain the wrist pin. the Fox .45 uses the same method of pin retainment. it saves wrist pin circlips from popping out into the transfer ports and ruining the sleeve.
