FFL REQUIRED: This firearm must ship to a licensed FFL dealer. Federal law sets minimum age requirements, and every transfer requires a background check and all required ATF paperwork. State and local laws apply.

Shipping Policy

Firearms can only ship to a valid Federal Firearms License (FFL) holder — never directly to a residence. Provide your dealer’s FFL at checkout, or have them email a copy to us, and we’ll verify it before your firearm leaves our shop.

Every transfer requires a background check and the completion of all required ATF paperwork. Buyers must be at least 21 years old to purchase a handgun, and at least 18 years old to purchase a long gun.

Shipping is calculated at checkout. Local pickup is always available right here in Carthage.

Return Policy

Once a firearm has been transferred to you, federal law generally prevents us from accepting it back as a return.

If a firearm arrives defective, it’s handled through the manufacturer’s warranty — and we’ll help you coordinate that process at no charge.

Questions about any of this? Call us at (417) 358-5700 — see our Store Policies for full details.
