Hello, I've tried searching the entire website but I can't find the answer I'm looking for. I'm trying to find out what thread pitch is on my IWI Jericho 941s. It's not 1/2-28 that's a fact, I think it's M13.5x1RH or M13x1RH. Can anyone please help me out with this problem? Im sure I could take it to a machine shop and have it figured out, but thought I'd try and ask here before I drive an hour to try and figure it out.
