Piston CNC with 19 steel teeth - POM - RetroArms

Next-generation pistons with a completely redesigned structure and design, and newly used materials.

The piston body is completely manufactured by CNC milling from a block of extremely durable material, POM-C. This material is highly resistant to mechanical stress and abrasion, withstands high loads, has a wide operating temperature range from -60 °C to +100 °C, has minimal water absorption compared to other plastics, and withstands long-term oiling.

The piston body is connected under the first pickup tooth by a massive bridge, so there is no risk of the rack falling out under high load. The piston rack is seated in grooves, so it cannot lift during firing.
