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.

Good for a small to medium dog
Color: Squirrels (3-pack)
These replacement ones were bigger than anticipated but work well for my small dog. Pretty durable (and she likes to destroy toys)

Perfect Toy for the Picky Dogs!
Color: Squirrels (3-pack)
These are replacement squirrels. I had these for my own dogs. When I noticed how much enjoyment they got out of them, I purchased them as gifts. My brother’s 20 lb dog is so picky, but I took a chance. The squirrel toys are the only ones he plays with. According to my brother, his dog ignores treats and toys, but loves the squirrels. A friend of mine said the same thing. She also has small dogs, 25 lb & 30 lb. They preferred the squirrels. This toy is not for big dogs. Unless they’re gentle, they will probably be torn apart very quickly. They are very easy to chew on, the squeak isn’t loud, there’s no smell and very entertaining!

Dog Approved
Color: Squirrels (3-pack)
The toys are soft but well made, and my dog really likes that they squeak. He loves carrying them around and hunting for them when I hide them.

Super Sturdy with hours of fun.
Color: Wild Duck, Hare, Squirrel & Alligator, Size: Small
I got the small ones that you cannot put a water bottle in. These toys have held up way better than expected. I am dog sitting a very rough with toys dog named Chunk. He tears up ever. Single. Toy my dog (Ted) has. I bought new ones just for chunk. These appealed to me with the no stuffing, They were cheaper, and have a squeaker. Everything chunk needed. They arrived on time and I thought I wasted my money. They were super soft, like too soft. They felt flimsy and weak. Like 5 minutes with chunk and they be dead. 2 hours with my dog and they would have a rip. So far 2 of them (I set two out) have lasted the whole weekend. The bunny looks very rough and disgusting, but no rips, the squeakers still work, and no random fluff everywhere. I am going to wash the bunny once chunk leaves. My very careful doggo Ted loves them too. He throws them up in the air and catches them, plays tug of war with them, and no rips. They are super sturdy. He can’t wait until Chunk leaves (chunk is 2 and Ted is 12-13) so he can play with them.
