Purchasing a shipping label through Rugged Suppressors is the most secure way to return your suppressor to us for service repairs. Due to shipping carrier regulations, ATF rules, and other contributing factors; we recommend this as the most compliant and safe option. Please only purchase this label, do not add other items from the eStore. Upon purchasing this label, the Rugged Customer Service Department will email you a UPS label to print and adhere to your package. Write your Service Authorization # on the box and drop off at a UPS Customer Center.
