Returns
We are committed to ensuring your satisfaction. If you find any non-firearm merchandise defective upon receipt, we will gladly accept returns and provide your choice of a replacement item (subject to availability) or a full refund. Please note that Arm Safe Supply cannot be held responsible for items damaged during shipping. In such cases, we kindly ask you to file a claim with the carrier. Should you receive a defective item, please call us immediately at +1 713 766 9931 to request a return label.
Important Information for Firearm Returns
We kindly request that you thoroughly inspect all firearms before proceeding with the transfer. Once a new firearm is transferred to you, it is considered used, even if it remains unfired. As a result, we are unable to provide a full refund for new firearms after they have been transferred into your possession. Please note that we do not reimburse FFL transfer fees on returned items.
We understand that some manufacturer defects may not be identifiable during the initial inspection. If you discover a defect after the transfer, the firearm must be returned directly to the manufacturer for replacement or repair in accordance with their warranty policy. This approach allows you to avoid the additional transfer fees associated with returning the firearm to us through your local FFL dealer.
Please do not send defective firearms directly to Arm Safe Supply. Manufacturer-repaired firearms can be returned directly to you without additional FFL transfer or associated fees. However, if the manufacturer decides to replace the firearm, the replacement must be transferred through your local FFL dealer to document the new serial number.
