The new MK3. Now available and fully compatible with the Infinity version!

 

New MK3 features:

  • Removable front cap positioning pins for the new Infinity HOP-UP unit
  • Enlarged slot for the Infinity gearbox
  • Still compatible with pre-2021 Systema gearboxes

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.

Cute, Comfortable, and Kid-Approved
Size: 10 Toddler, Color: Pink
These Amazon Essentials hook-and-loop athletic sneakers are very pink, so they may not immediately read as “unisex” in color. That said, at this age range, kids’ shoe sizing is the same for boys and girls, which is likely what the unisex label refers to. The shoes fit true to size and are well made. The craftsmanship is solid, with neatly applied seams and glue and no rough edges. The stretchy laces are permanently closed, which keeps them tidy, while the Velcro strap opens wide enough to make it easy for kids to put their feet in and take them off independently. Comfort-wise, these are a win. The inner heel has good cushioning so the shoes don’t rub or scrape the foot. The insole is flat but soft, and the toe box shape works well for most foot shapes. My granddaughter finds them very comfortable for everyday wear. The uppers are made from a nylon-type material combined with soft faux suede, which gives them a nice look and feel. Overall, these sneakers are cute, comfortable, and well made for the price, making them a great everyday shoe option for toddlers and kids.

These Amazon Essentials sneakers are really nice! The quality is very good, and the size fits perfectly. The color looks exactly like the picture, which I appreciate. They’re lightweight, not heavy at all, and my child walks comfortably in them. They also look very cute and go well with different outfits. Pros: • Good quality material • True to size • Lightweight and comfortable • Color matches the photos • Stylish design for kids Cons: • The soles could be a little softer for extra comfort Overall, these are great everyday shoes for kids affordable, comfortable, and they look great
