The piston head body is machined from aluminium with excess material removed to minimise weight and a full radius o-ring groove to spread the impact force and maximise durability, a seperate slimmed down aluminium core and non-bearing type bushing help to maximise durability while keeping the overall weight down. For springs over M120 an aluminium piston head is recommended.
