If you have not accepted the firearm from the FFL holder contact buds if you have taken possession see the below buds policy
NEW FIREARM RETURNS
VERY IMPORTANT - FIREARM RETURNS!! Please take your time to inspect all firearms thoroughly BEFORE proceeding with the transfer. Once a new firearm is transferred to you, it is considered used, even if unfired. Consequently, we cannot accept returns on firearms once they have been transferred into your possession. Also, we DO NOT reimburse FFL transfer fees on returned items. **Upon discovering a defect AFTER the transfer, the firearm MUST be returned directly to the the manufacturer for replacement or repair (in accordance with manufacturer's warranty policy). By sending a defective firearm directly to the manufacturer, you can avoid the unnecessary transfer fees associated with returning the firearm to us through your local FFL dealer. Manufacturer repaired firearms can be returned directly to the customer without additional FFL transfer or associated fees. BudsGunShop.com will provide a prepaid label to ship the firearm to the manufacturer, if a prepaid label is not covered under their warranty.
