Hi Ben, that all depends on the reason for the refusal. If you simply changed your mind or ordered the incorrect item, there will be a restocking fee. If the gun is difective or not as advertised, there will be no restocking fee.
Stay safe, and have a great day!

No restocking fees. The link below is all you'll need to know about Buds return policy.
