This piston literally ticks every single box for the ultimate AEG Piston.

Custom made Fiber reinforced PA66 Polyamide (Nylon) Lightweight Piston, CNC head, with your choice of SHS or CNC cut rack, strengthened and weight reduced with large windows in the low stress areas, with total weight is under 27.5 grams, this is DSG and high rate of fire ready out of the box.

We have over engineered the piston as much as physically possible. Nearly doubling the amount of material to the highest stress point at the back of the piston bridge to increase support for the pick up tooth with 80% more material than every other piston we have measured and tested. We opted for Cr12MoV hardened steel as it is the strongest metal we could use to ensure maximum life and outright breaking strength. Then added in every piston head feature we could, all this culminates in the ultimate piston!

Manufacturer: Aztech Innovations


Compatibility: Most Airsoft AEGs
Material: Steel, High Strength PA66 Polyamide

NOTE: It is highly recommended to bond the steel rack to the body of the piston for high performance builds. We recommend a using JB Weld Original Steel reinforced Epoxy for the highest strength bond available Or at very least high strength Gorilla Grip 2 part araldite epoxy.
