In some situations we are unable to ship an item because our shipping partners require us to restrict it to ground transportation only (the FAA will not allow them to transport it on an airplane).
Examples include: Hazmat, CO2, air guns that contain pressurized chambers (some PCP guns).
If you have a restricted item on your order, we can only provide ground shipping options. Sometimes you live in a place that does not have guaranteed ground delivery, and in this instance we are not able to ship the restricted items to you.
You can remove the restricted items if you would like to receive the items on your order that are allowed to be sent via non-ground delivery.
