Terms and Conditions

Must agree with Terms & Conditions to complete order:

All firearms and accessories listed on this website are Factory NEW IN BOX, complete with all factory included parts, accessories, literature, packaging, etc. In order to save time, we generally use “stock photos” of the products that are listed. As such, these pictures generally do not include items such as the box, manual, or included accessories. They also do not necessarily accurately represent details such as wood grain or wood color, as these details will vary widely. Unfortunately we are unable to guarantee any particular finish or wood grain pattern!

Purchasing a firearm online is simple and very similar to any online shopping experience. The difference is that we cannot send the firearm to you. Instead, we have to send the Firearm to a Local Gun Shop or FFL Dealer near you, and you pick your product up there.

We only need two things from YOU to complete and process a firearm purchase online:

Method of Payment. Federal Firearms License (FFL): We will ship to a local FFL dealer of your choice. Any legitimate gun store and/or gun dealer has an FFL license. You can also check with your local pawn shops.

How to arrange a shipment and transfer:

Find a licensed FFL Dealer in your area: Ask the dealer about their FFL transfer fee (usually around $25.00, but varies by dealer). Provide your dealer with our fax number (435-938-9816) or Email (123FFL@gmail.com) where they can send a copy of their FFL (if not already on file). To Help Speed Up Your Order : Please ask your FFL Dealer to write your Order Number, Name, and Firearm on any corresponding paperwork you or your FFL may send us. AK, HI and other outlying areas have a higher shipping rate.

We accept payment via Credit Cards- Visa, Mastercard, and Discover.

To Help Speed Up Your Order: Please ask your FFL Dealer to write your Order Number, Name, and Firearm on any correspondence you or your FFL may send us.

Orders are generally shipped within 5-7 Business Days from the time the order is completely processed (payment received for order, and a copy of your dealer’s FFL on file).

The number of days UPS / USPS counts to deliver a package is based upon “Business Days.” A business day does NOT include Saturday, Sunday, National Holidays, and the day the package was picked up on. For example, if you package was picked up on Tuesday for 2nd Day Air delivery, the package will arrive on Thursday, since Tuesday does not count as a delivery day.

IMPORTANT: When you pick up the firearm at your FFL, please inspect the product thoroughly and confirm that this is the product you ordered, and that there are no defects. If there are any problems with your purchase, simply Do Not Accept The Transfer. We will gladly have the firearm shipped back to us at our expense and provide you with your choice of a replacement or full refund.

Any Firearm that you have accepted and transferred from your dealer is NON-RETURNABLE and NON-REFUNDABLE.

CUSTOMERS ARE RESPONSIBLE FOR VERIFYING THAT THE FIREARM YOU ORDER IS LEGAL IN YOUR STATE. In the case that a firearm has been shipped to to a state where the firearm is not legal, the customer will be charged for the return shipping fee, and a 15% restocking fee.

Once you accept transfer, the gun is considered used and must be returned directly to the manufacturer for warranty repair or replacement.

In the case that a customer is declined in their ATF Form 4473, the customer is responsible for the shipping fee of returning the firearm, along with a 15% re-stocking fee.

All other merchandise returns: Original shipping and handling fees are not refundable. Offers are subject to adjustment due to returns, cancellations, and exchanges.

For Pick Up In-Store Orders: Orders placed through our TSSWarehouse website generally take around 3 to 5 business days before they are available to be picked up at our Tooele, UT location. All walk-in traffic to this location is strictly by appointment only. We will contact you by phone or email to let you know your order is ready for pickup.
