The new MK3 is 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 cylinder version retains all the advantages of the MK1.

We improved the inner wall surface of both the piston and the cylinder to make it smoother and reduce resistance.

We now use higher-quality rack gears and NBR rubber.

 

It was the best—now it’s even better.

 

 

--------------------------------------------

 

Tired of losing the index screw? Or tired of adjusting the weak, 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 0.2g 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

*Notice: BCGS is only compatible with the HAO Advanced PTW Cylinder with a pre-milled 0.2mm deep slot for easier insertion/removal without damaging the sticker.


*Notice: Fire the first 500 rounds gently to achieve optimal sealing and performance.

Decent Shoes with Misleading Description (Not Leather)
Size: 12 Wide, Color: Black, Size: 12 Wide, Color: Black
I only look for leather when I’m purchasing dress shoes. Under the description “details” on this item it lists the shoe as leather upper and inner lining. A photo shows “genuine Napa leather lining”. If you keep reading (which I have now that I’ve received the shoes) it shows “faux leather” in the small print and that is not “leather”. I run a small leather business and this irks me because it’s clearly false advertising. The details also show the product is made in Brazil but when they arrived today, the shoe tag shows “Made in China” and “Man Made upper and lower”. I don’t hate the shoes. They look nice. What I know is they won’t hold up over time like leather, which is why the description should be accurate and not misleading.

Fits good just needs a light ironing.
Good fit with a casual look. These are a nice fit with an almost slim fit width at the bottom. I am a short guy and the 34x28 size fit me great. As I obviously don't have a trim waistline, I like that the bottom of these are narrower than a more dressier pant. The waist of my pants tend to move up and down approx. an inch to inch and a half and slacks tend to get under the heel of the less clunky modern dress casual shoe. Comparison below. Amazon Essentials 34x28 were a lot tighter (like a 32)in the waist and the length seemed loo long.
