These pistons are made for extended gearboxes like those found in SR-25s and L85s. These seems to be just extended copies of the well proven 15T pistons. It's 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. Since it does have all 19 teeth you'll have to remove tooth before the pickup tooth and maybe half of the one before that to fix angle of engagement. Note: To increase this piston's amazing strength even more you can use some ultra thin cyanoacrylate adhesive (super glue) and wick it in around the piston rack.
