The spring is a out dated version of the power tube spacer, which is what AGD used before the spacer came along. Its always wise to have some various sized spacers on hand, incase you buy some new parts for your mag and need to adjust your spacer length, theyre quite handy from time to time.

If the spring is working fine for you, its not really a huge deal whether your using a spacer or spring. As far as I know at anyrate. :D
