This is a set from GMT with a 15T piston and an aluminum ball bearing piston head. The piston is made of fiber reinforced Nylon and has a full rack of steel teeth. If you need maximum strength and durability this is what you want. The aluminum piston head is pretty standard as piston heads go, the thrust ball bearing releases torsion in the spring acts as a spring spacer to increase FPS. Since the rack does have 15 teeth you'll have to remove the tooth before the pickup tooth and maybe half of the one before that to fix angle of engagement, if you don't want to or can't do this adding the AoE fix item to your cart you can have this done for you or just get one of the 14 tooth pistons instead.
Install notes: To increase this piston's amazing strength even more you can use some ultra thin cyanoacrylate adhesive (super glue) to glue the rack in place along the rails and seat it better at either end. As with all piston heads it's recommended you use some loctite when securing the piston head to prevent it unthreading itself during operation.
