It is true that the recoil pad uses springs. As such, the pad really, really works.
I'm not quite sure how I can answer the question of whether the pad is durable because I have only had it on my gun for about 2 years. During that time, it has held up very well with no problems and no signs of wear. Then again, since I own many rifles, I don't use these particular guns with the Answer System very much either.
