The rubber tip goes against the magazine cap. This is to prevent "oil leeching" from metal-to-wood contact, whereas the other end of the plug dead stops, when fully loaded and over-compressed, against the plastic follower. It's nice to throw a wider plastic flange on the cap end of your plug, so your spring can pin the plug in position and prevent rattling.

It's pretty minimalist all right. If you have one of these, shake it out of the mag tube and bevel the ends. If left square it's possible for them to get tangled in the mag spring, turning your repeater into a single shot.The simplicity and basic form of the Mossberg 500 plug is seriously cool to me. I'm not kidding.
