You may return most new, unopened items within 30 days of delivery for a full refund. We'll also pay the return shipping costs if the return is a result of our error (you received an incorrect or defective item, etc.).
You should expect to receive your refund within four weeks of giving your package to the return shipper, however, in many cases you will receive a refund more quickly. This time period includes the transit time for us to receive your return from the shipper (5 to 10 business days), the time it takes us to process your return once we receive it (3 to 5 business days), and the time it takes your bank to process our refund request (5 to 10 business days).
If you need to return an item, simply login to your account, view the order using the "Complete Orders" link under the My Account menu and click the Return Item(s) button. We'll notify you via e-mail of your refund once we've received and processed the returned item.
We can ship to virtually any address in the world. Note that there are restrictions on some products, and some products cannot be shipped to international destinations.
When you place an order, we will estimate shipping and delivery dates for you based on the availability of your items and the shipping options you choose. Depending on the shipping provider you choose, shipping date estimates may appear on the shipping quotes page.
Please also note that the shipping rates for many items we sell are weight-based. The weight of any such item can be found on its detail page. To reflect the policies of the shipping companies we use, all weights will be rounded up to the next full pound.
How To Buy A Gun
We can only ship guns to licenced firearm owner's living in New Zealand.
If you do not have a licence then consider applying. The process is outlined here on the NZ Police website.
All firearms and serialised receivers require a mail order form to be completed. Download the mail order form here , print it, and take it to your local police station. The police officer receiving it will then validate your licence, sign / stamp it and email a scanned copy of the form to us. Once we receive the mail order from the police we will disptach the firearm or receiver.
We do not stock E Category firearms but can act as your agent for import. However we recommend using the POL67X method instead as being quicker and more reliable than applying to police for an import permit. You can download a POL67X form here.
