Not shipped yet: we can usually cancel it, but there's no self-service cancel button — email or call support@hkparts.net or (801) 987-3494, Mon–Fri, 8:00am–3:00pm MST right away, since most orders ship the next business day (same day if expedited and placed before 2:00pm MST).

Already shipped: it can't be canceled. Once it arrives, unused items in 100% new condition can go through the Return Portal for store credit.

Refunds on pre-shipment cancellations go to your original payment method and typically post in 5–10 business days. If it's canceled the same day it was placed, your bank may instead just void the pending charge rather than post a separate refund.

None of these are self-service changes once an order is submitted — they all depend on catching the order before it ships.

Not shipped yet: email or call support@hkparts.net or (801) 987-3494, Mon–Fri, 8:00am–3:00pm MST immediately with your order number and the change needed.

Already shipped: the order itself can't be modified. For an address correction, contact the carrier directly — they can sometimes redirect or hold a package. For a wrong quantity or item, place a new order and return the original through the Return Portal once it arrives.

Check hkparts.net/status to see if it's shipped yet. If not, the fastest fix is placing a new order for the correct item and asking us to cancel the original.

If it's already shipped, this is handled as a standard return once it arrives — see returns & exchanges.

Check hkparts.net/status with each order number. If only one actually processed, the other was never charged — no action needed.

If both genuinely processed, email support@hkparts.net or (801) 987-3494, Mon–Fri, 8:00am–3:00pm MST with both order numbers so the duplicate can be canceled. The reversed charge typically appears in 5–10 business days.

1. Double-check the address is complete and accurately formatted — this is the most common cause.
2. Clear your browser's cache/cookies, or try a different browser or device.
3. Confirm your billing and shipping info match what your bank has on file.

Still stuck? Call (801) 987-3494 (Mon–Fri, 8:00am–3:00pm MST) to place the order by phone. We don't keep cards on file, so you'll re-enter payment details at that time.

Depends on the item and your state. Items that don't legally require FFL transfer ship straight to your door (signature required, 21+) even in restricted states — asking to route a non-FFL item through an FFL anyway just adds cost.

Restricted items (like large-capacity magazines) need valid LE credentials or an FFL/SOT on file before they can ship to certain states. See state & legal restrictions for the current list and how to submit documentation.
