Terms of service

Last updated: September 28, 2026

1. Agreement

quadradyn.com and the Quadradyn online store (together, the “Site”) are operated by Quadradyn LLC (“Quadradyn,” “we,” “us”), a federally licensed firearms manufacturer headquartered in Pompano Beach, Florida. By visiting the Site, sending a message, requesting a quote, registering for briefings, creating an account, or placing an order, you agree to these Terms of Service and to our Privacy Policy, Shipping Policy, and Return and Refund Policy (together, the “Policies”). If you do not agree, do not use the Site.

2. Eligibility

You must be at least 18 years old to use the Site and to buy merchandise or non-serialized components. You must be at least 21 years old to buy ammunition or a firearm from Quadradyn, and you must be legally eligible to receive and possess the item under federal, state, and local law at the delivery address. By placing an order you represent that:

  • you are not prohibited from possessing firearms or ammunition under 18 U.S.C. § 922(g) or (n), or under the law of your state;
  • you are buying for yourself and not for anyone else (a “straw purchase” is a federal felony);
  • the item is lawful to own, and lawful to ship to, the address you provide; and
  • every detail you give us, including your age, identity, address, and receiving dealer, is accurate.

3. Orders, pricing, and acceptance

An order is an offer to buy. The confirmation email you receive acknowledges your order; we accept it when we ship, or, for a firearm, when we have verified your receiving dealer and ship to it. We may accept, limit, or decline any order for any lawful reason, including inventory, a pricing or listing error, suspected fraud, a restricted destination, or an inability to verify your eligibility or your receiving dealer, and we may limit quantities per order or per customer. Prices are in U.S. dollars and exclude sales tax, shipping, your dealer’s transfer fee, and any federal tax stamp. Sales tax is calculated at checkout and collected where the law requires. Prices, specifications, availability, and lead times can change without notice; if we cannot honor a price or specification shown when you ordered, we will tell you before charging you or refund you in full.

4. Firearms and ammunition compliance

Quadradyn LLC holds a Federal Firearms License issued by the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) as a Type 07 Manufacturer of Firearms, and is registered and pays the Class 2 Special Occupational Tax as a manufacturer of National Firearms Act firearms, both for our licensed premises in Pompano Beach, Florida. For security, our license number and street address are not published online. Licensed dealers and distributors who need our license for a transfer can request a signed copy from compliance@quadradyn.com and verify it through the ATF’s FFL eZ Check system. Every sale is made under the following rules.

  • Serialized firearms transfer only through a licensed dealer. A firearm you buy online ships only to a Federal Firearms Licensee (FFL) you select, never to a residence. You complete ATF Form 4473 and the background check at your dealer and pay the dealer’s transfer fee directly to the dealer. Transfers made in person at our licensed premises follow the same federal requirements, plus the background check conducted through the Florida Department of Law Enforcement and Florida’s mandatory waiting period. No transfer is made to a person we know or have reason to believe is prohibited.
  • National Firearms Act items (for example short-barreled rifles and suppressors) transfer only through a dealer that holds a Special Occupational Tax registration, and only after the ATF has approved the transfer and the tax stamp has issued. NFA processing times are set by the ATF, not by Quadradyn.
  • Every firearm we sell is serialized and marked as ATF Final Rule 2021R-05 and 27 CFR 478.92 require. We do not manufacture, sell, or ship unfinished, partially complete, or “80%” frames or receivers, or the jigs, templates, or parts kits that the rule treats as firearms. Upper receivers, barrels, handguards, and similar parts are components and are sold and shipped as components.
  • Ammunition is sold only to buyers 21 years of age or older, ships by ground only to the buyer’s own street address with an adult signature required at delivery, and does not ship to Alaska, California, Connecticut, the District of Columbia, Hawaii, Illinois, Massachusetts, New Jersey, or New York. The full list, with the reason for each restriction, is in our Shipping Policy. Checkout enforces these rules before an order is accepted.
  • Barrels shorter than 16 inches. Installing a barrel shorter than 16 inches on a rifle-configured firearm creates a short-barreled rifle regulated under the National Firearms Act, which requires ATF approval before assembly. Confirm that the barrel, and the firearm it will go on, are lawful where you live before you order.
  • Records and cooperation. Acquisition and disposition records, ATF Forms 4473, and NFA records are kept in the form and for the period federal regulations require. We answer ATF trace requests within the time the law allows, cooperate fully with law enforcement, and refuse any sale that looks like a straw purchase or an attempt to evade the law.
  • Exports. We do not export. Our products are subject to the Export Administration Regulations or the International Traffic in Arms Regulations and may not be exported or re-exported without government authorization.
  • What you confirm at checkout. That you meet the age requirement for the product, that you are not prohibited from possessing it, that you are buying it for yourself, and that it is lawful to own and to receive at the delivery address. Buying a firearm or ammunition for someone else, or lying on any purchase or transfer document, is a federal crime.

Firearms and ammunition law changes often and varies by state, county, and city. These Policies describe Quadradyn’s practices; they are not legal advice and cannot substitute for knowing the law where you live. When in doubt, ask your receiving dealer or a lawyer in your state before you order.

5. Product information

Product descriptions, ballistic figures, and performance data are published in good faith and may be modeled, provisional, or drawn from published third-party data, as noted on the product page. Final specifications follow the production configuration. Nothing on the Site promises a particular result in a particular rifle, and nothing on the Site replaces the safety, handling, and maintenance instructions supplied with a product. Firearms and ammunition are dangerous if misused. Use them only as instructed and only in accordance with the law.

6. Intelligence content and third-party marks

Quadradyn Intelligence articles are editorial analysis built from open sources. They are not legal, technical, or professional advice, and references to any government, agency, or military unit describe published history only; no endorsement of Quadradyn is stated or implied. Third-party names and marks belong to their owners. ICAR is a trademark of SureFire, LLC; PMAG is a trademark of Magpul Industries; Sabre is a trademark of Palmetto State Armory. Quadradyn is not affiliated with any of them.

7. Intellectual property

The Site, its design, text, images, data, and code, and the Quadradyn name, logo, and product names are owned by or licensed to Quadradyn and protected by United States and international law. You may view and print pages for your personal, non-commercial use. Any other reproduction, distribution, scraping, or commercial use requires our written permission.

8. Your submissions

Anything you send us through our forms, by email, or through the store, including photographs for a finishing or purchasing quote, must be accurate and yours to share. You grant Quadradyn a non-exclusive license to use it to respond to you, prepare your quote, perform the work you request, and keep the records the law requires. Do not send content that is unlawful, that infringes someone else’s rights, or that contains another person’s personal information without their consent.

9. Customer accounts

If you create a customer account, keep your sign-in details confidential and tell us promptly if you believe they have been compromised. You are responsible for activity under your account and for keeping its details accurate and current, including your shipping address and receiving dealer. We may close an account that is used in breach of these Policies.

10. Acceptable use

You agree not to interfere with the Site or its security, submit automated or bulk requests, misrepresent your identity or eligibility, attempt to buy on behalf of a prohibited person, or use the Site to break any law. We may suspend access and cancel orders to protect the Site, our customers, or the public.

11. Third-party services and links

Our online store is hosted by Shopify Inc., and checkout, payment, and delivery run on third-party services: Shopify’s platform, our payment processor, and our carriers. Their terms govern their part of the transaction, and your card details are handled by the payment processor, not by Quadradyn. Links to outside websites are provided for convenience; we do not control them and are not responsible for their content.

12. Disclaimer and limitation of liability

The Site is provided “as is” and “as available.” To the fullest extent the law allows, Quadradyn disclaims all warranties about the Site itself, express or implied, and is not liable for indirect, incidental, consequential, or punitive damages arising from the Site or any order. Our total liability for any claim related to an order is limited to the amount you paid for that order. Product warranties are separate; they are described in our Return and Refund Policy and in the documentation supplied with the product. Some jurisdictions do not allow certain limitations, and in those places our liability is limited to the greatest extent permitted.

13. Indemnity

You agree to defend and hold Quadradyn, its owners, and its staff harmless from claims, losses, and costs arising from your misuse of the Site, your breach of these Policies, or your violation of any law, including any misstatement of your eligibility to buy or possess a product.

14. Governing law and disputes

These Policies are governed by the laws of the State of Florida and applicable federal law, without regard to conflict-of-law rules. Write to our legal desk at legal@quadradyn.com first; most concerns are resolved within thirty days. Any dispute that is not resolved informally will be brought exclusively in the state or federal courts located in Broward County, Florida, and you consent to their jurisdiction and venue.

15. General terms

These Policies are the entire agreement between you and Quadradyn about the Site and your orders. If any provision is found unenforceable, the rest remain in effect. Our not enforcing a provision on one occasion is not a waiver of it. You may not assign your rights under these Policies; we may assign ours to a successor to our business. You agree to receive order confirmations, shipping notices, and other transactional messages from us electronically at the email address you provide.

16. Changes to these Policies

We may revise these Policies by posting a new version with a new date. The version in force when you place an order governs that order. Continued use of the Site after a change means you accept it.
