Got the older version of this and it’s a must have if you have a hpa upper

Skeleton purple gearbox, the highest quality gearbox you’ll find on the market, straight from airtac customs with no fuss.

Even though it’s the gen 1 Airtac gearbox still functions amazingly for gen 1 I can’t imaging how good the gen 3 is!

I’ve taken all the gearboxes out of my build and replaced them with AirTac gearboxes. I have gearboxes from gen1 to gen 2 v2. I love the constant improvement of these gearboxes, how light weight they are, and all the applications they fit. I will continue to chose these gearboxes over any other.

The AirTac gearbox is lightweight and durable. I highly recommend this gear box if you’re running a AirTac CRBN upper. You even have room to put a battery in the top of the gearbox too.

Trigger board screw is too long it scrapes my selector plate

Vraiment facile à monter, très bonne ajustement du nozzle

quality of the gearbox is great, just perfect for my polarstar build. adjusting things was easy and placement fit just right. the window made instaling the end cap much easier haha but also it kept nice and aligned with the airtac upper. definitely must have
Matthew Jalette
This gearbox is perfect for any application. Very well made. Easy install. I own 3 of them now!

Worked with my airtac upper perfectly that I bought at the same time. Whole set up shoots Lazer beams, literally. Highly recommend and the staff is knowledgeable and kind. This is the setup to have with Airtac parts for the new season.

I love this gearbox as it is easy to install and it makes the install of the CRBN upper much easier.
