The MK3. HAO’s cylinder version retains all the advantages of the MK1.
We improved the inner surface of the piston wall and cylinder for smoother operation and reduced resistance.
We now use higher-quality rack gears and NBR rubber components.
It was the best—and now it’s even better.

Tired of losing the indexing screw? Or tired of adjusting the weak and wobbly aluminum extrusion rail inside the cylinder?
Introducing the HAO Advanced PTW Cylinder.
A cylinder that combines HAO’s latest technology in:
- One-piece SUS303 cylinder body with precision EDM wire-cut piston rail.
- Upgraded injected polymer piston.
- SUS303 anti-torsion spring rotation bearing system.
- Heat-treated S45C EDM wire-cut rack gear.
- Upgraded SUS303 nozzle.
- All redesigned and reinforced NBR rubber components and O-rings.
- BCGS (Bolt Carrier Group Sticker) makes your PTW look more like a real steel (RS).
MPS/FPS conversion: (calculated with 6mm 0.20g BBs)
M90 = 296.00 FPS = 0.81J
M110 = 361.84 FPS = 1.21J
M130 = 427.63 FPS = 1.69J
M150 = 493.42 FPS = 2.25J
*Note: BCGS is only compatible with the HAO Advanced PTW Cylinder with a pre-milled 0.2mm deep slot to allow insertion/removal without damaging the sticker.
*Note: Fire the first 500 rounds gently to achieve optimal sealing and performance.
