Shipping Restrictions

It is the customer’s responsibility for understanding state laws regarding all purchases made. For a comprehensive list of all Shipping Restrictions, please refer to our Shipping Restrictions By State Page found Here.

All NFA Rules Apply

These items are controlled by the U.S. Government and authorized for export only to the country of ultimate destination for use by the ultimate consignee or end-user(s) herein identified. They may not be resold, transferred, or otherwise disposed of, to any other country or to any person other than the authorized ultimate consignee or end-user(s), either in their original form or after being incorporated into other items, without first obtaining approval from the U.S. government or as otherwise authorized by U.S. law and regulations.

Local Law Compliance

Certain firearm parts and accessories, including AR-style upper receivers, are subject to complex and frequently changing federal, state, and local laws and regulations. While an upper receiver may be lawfully sold and shipped as a component, the legality of possessing, assembling, configuring, or using an upper receiver in certain states (e.g., California, Washington State) and localities depends on how it is assembled, combined with other components, and ultimately used. You are solely responsible for ensuring that any assembly, configuration, possession, or use complies with all federal, state, and local laws, including any so-called “assault weapon” bans and short-barreled rifle restrictions. We do not provide legal advice and are not responsible for unlawful configurations or uses.

WARNING: Handling firearms or firearms parts can expose you to lead and other petroleum products known to the State of California to cause cancer, birth defects, or other reproductive harm. Wash hands thoroughly after handling. For more information go to www.p65warnings.ca.gov (CA Health and Safety Code Section 25249.6).

Warranty

Palmetto State Armory firearms are covered by an industry-leading Full Lifetime Warranty. This extends beyond the original purchaser. We want the person who bought a great quality firearm at an excellent price to have comfort in knowing that, if an issue arises due to a defect in materials or workmanship, we will make it right, consistent with this warranty.

We strive for excellence all the way through production and hope customers never have to use this warranty. We also pride ourselves in a 99% non-repair/non-return ratio, but this warranty is here for peace of mind so that the customer can be confident in their purchase.

For the Life of Our Product

Firearms and parts manufactured by Palmetto State Armory are backed by our Full Lifetime Warranty. Our PSA manufactured firearms and parts are warranted to be free from defects in materials and craftsmanship for the serviceable lifetime of the firearm or part. The liability of Palmetto State Armory under this warranty shall be limited solely to the obligation to repair the defect, replace the firearm or part, or provide a refund, and to pay transportation and insurance charges for any return of the firearm to the owner for a rightful warranty claim. This warranty is transferable for the serviceable lifetime of the firearm or part.

What We Don't Cover

This warranty does not cover ordinary wear and tear or any damage resulting from careless or criminal handling, abuse, neglect, corrosion, unauthorized or improper modifications, including modifications using non-PSA or otherwise incompatible parts, unauthorized or improper repairs or adjustments, use of improper, substandard, reloaded, or defective ammunition, or other unauthorized or unreasonable use of the firearm or firearm part. Palmetto State Armory disclaims all responsibility and liability for any damage caused as a result of third-party accessory use.

This warranty is offered solely to individual consumer (civilian) customers. It does not apply to government or non-civilian customers. This warranty is valid only for residents of the United States (excluding territories) and applies only to firearms and parts purchased, located, and used within the United States. We do not accept returns for, and will not repair or replace, any firearms or parts purchased, located, or used outside the United States.

Palmetto State Armory, in its sole discretion, will determine if a particular issue or condition is covered by this warranty.

Initiating a Warranty Claim

To initiate a warranty claim, please use the Contact Form and select "Problem with a PSA Product" as your Contact Reason. Warranty claims must include a completed RMA form in the box with the returned firearm or part. All complete firearms need to be returned in full for repair. Replacement parts will not be issued or sent to the customer. The firearm or part concerned must be shipped using the prepaid label that our representative emails to you. Palmetto State Armory will pay shipping and insurance charges for the return of a firearm or part to its owner or FFL, if the related claim is a proper claim for warranty work. If Palmetto State Armory is unable to fix the original serial number, a new one will be sent out but must go to an FFL for transfer back to the customer. Another background check will be completed at the time of transfer. Palmetto State Armory is not responsible for transfer fees at the FFL.

The remedies described above are your sole and exclusive remedies and Palmetto State Armory's entire liability for any breach of this Full Lifetime Warranty. Palmetto State Armory shall not under any circumstances be liable for any consequential, incidental, special or punitive damages or losses, whether direct or indirect.

Some states do not allow the exclusion or limitation of incidental or consequential damages, so the above limitation or exclusion may not apply to you.

This Full Lifetime Warranty gives you specific legal rights and you may also have other rights, which vary from state to state.
