CNC piston with steel comb (14,5 teeth) - POM - RetroArms

New generation piston with completely redesigned design and construction and newly used materials. The piston body is completely made by CNC milling from a block of extremely durable POM-C material. This material is very resistant to mechanical stress, abrasion, withstands high loads, has a large temperature range of use permanently from -60 ° C to +100 ° C, compared to other plastics has minimal absorbency and can withstand long-term oiling.

In addition, thanks to CNC milling, the body is very precise and straight, it does not have dips and shape irregularities as we know from plastic injection into the mold. The piston core is connected under the first pick-up tooth by a massive bridge, so there is no risk of the ridge falling under high load. The ridge of the piston is seated in the grooves, so it is not possible for it to lift when firing.
