Tired of losing the index screw? Or tired of adjusting the weak and wobbly aluminum extrusion rail inside the cylinder?

Introducing the HAO Advanced PTW Cylinder.

The cylinder that combines HAO’s latest technology in:

 

  • One-piece SUS303 cylinder body with precision wire-cut EDM piston rail.
  • Upgraded polymer-injected piston.
  • SUS303 anti-torsion spring rotation bearing system.
  • Heat-treated S45C wire-cut EDM ladder gear.
  • Upgraded SUS303 nozzle.
  • All NBR rubber parts and O-rings redesigned and reinforced.
  • BCGS (Bolt Carrier Group Sticker) makes your PTW look more like 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 featuring a pre-milled 0.2mm deep slot for easy insertion/removal without damaging the sticker.


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

Game changer for my truck
Size: 1.9" x 9.9" x 11.4"
I installed this K&N Lifetime Cabin Air Filter in my 2016 F-150 and noticed the difference right away. The airflow is stronger, and the cabin smells fresher even when driving through dusty or humid areas. What I really like is that it’s washable and reusable—so I won’t have to keep buying filters every year. Fitment was perfect and install took under 10 minutes. Just pop out the old one, slide this one in, and you’re good to go. It feels solid and well made, not like those cheap paper ones. It’s definitely worth the investment, especially if you drive a lot or have allergies. Highly recommend for anyone with a Ford or Lincoln vehicle—it pays for itself quickly!

nice quality
Size: 1.9" x 9.9" x 11.4"
I happen to be a fan of K&N air filters. Fit perfect in my vehicle. Seems like a much nicer quality filter than the cheapo filters from the parts store.
