The arms are made of thin walled 1 inch square aluminum tubing. After 80 shots there is no sign of any wear and tear on the arms. We used thick wall on our practice bot and noticed a substantial reduction in performance.
There are JVN style pegs to the back made of schedule 40 fiberglass tubing (PVC would work just as well). We are stilll determining the optimal lenth.
