I was just looking at the Aero Pack Retainer (54mm RA p) for the build I'm working on, with my first 54 MMT rocket. When I unscrewed the retainer cap there was a silver ring inside that came out. I have never seen this in my 29 and 38 mm retainers. Can someone tell me what this is for? The retainer is a little loose on the fiberglass MMT, is it a shim to take up some of the looseness?
