Bartamos, the new plug is as per this picture.
New version hollow palstic plug. It's the same length as the steel one and is capped at the ends. It's easier to make, lighter than the steel, won't rust, and I don't have to thread it. The cylinder/tube is double walled at the ends with a 1" internal shoulder so that the 1" external shoulder on the piston can't go past that point and slide out of the end of the cylinder (keeps everything contained within the cylinder when deployed).
