Notos Internal Porting

This service provides increased airflow and efficiency of the internal pathways, resulting in more power capability.

This is what we do to our Haji-Notos/Notos G2 Custom Builds, but you can have the same service performed on your Notos as well. We increase the internal transfer ports, which results in greater airflow and more power. This service also includes a trigger sear face polish to make the trigger feel much smoother.

Ship us your complete Notos/Notos G2, or just the action with the stock and barrel removed, and we’ll perform the service.

If you want to minimize shipping costs and you elect to ship just the action, follow the instructions below.

If you are shipping your complete Notos, ignore the instructions below and use your original Notos Box to ship your Notos.
- Notos Barrel Removal
Your barrel is easily removed by removing the 2.5mm pan-head screw on top of the Picatinny rail near the magazine opening. Once the 2.5mm pan-head screw is removed, there is a 2mm set screw below it that holds the barrel in the receiver block. Loosen the 2mm screw four revolutions and slide out the barrel.

Shipping

Shortly after you place your order for the service, we send you a notification with a copy of your invoice. Shortly after that, you will receive a detailed notification with the shipping information to ship us your barrel/action/PCP for modification.

Please keep in mind that if you have multiple services executed, you will be better served using our Builder service option, because it groups the services, resulting in only one shipping cost.
