This is a discussion on Winchester (Olin Mathieson) Parts within the Reference forums, part of the M14 M1A Forum category; My one and only Winny new in tube op rods next to an H & R for comparison.
I also thought it was strange that the pack of connector lock pins I gave one to USSF06 out of was a yellowish clear cellophane plastic bag compared to the regular VCI paper bags shown here. The cellophane bag was still strong and pliable upon opening. I've only ever seen SA use both also, I''m not sure about the other manufacturers.
I have both SA and winchester parts in the cellophane wrapping. Never seen any from the other manufactures.
This is a great thread with lots of great pictures.
