Frequently Asked Questions

Everything you need to know about FlashStrike shipping, products, and partnership opportunities.

Do you ship to my country?

We ship to all countries within the European Union. If you are located outside the EU, please get in touch with our customer support team, and we will work out an individual shipping solution for your order.

How long will it take to receive my package?

All orders are dispatched no later than the next business day. Once handed over to the courier, delivery timing depends on the specific carrier, but packages usually arrive within 3 to 5 business days.

Why are the shipping costs set at this rate?

To guarantee maximum speed and delivery safety, we provide a unified flat-rate shipping fee across all EU countries. However, if you wish to save on delivery fees, you can select Custom Shipping at checkout—we will calculate the exact shipping cost specifically for your location.

What warranty do you offer on FlashStrike grenades?

We provide a standard 2-year warranty on the complete mechanical functionality of the mechanism. Because our grenades feature an extremely resilient, all-rubber outer body, there is virtually no way to break them during regular airsoft gameplay or heavy tactical use.

How does the FlashStrike mechanical acoustic grenade work?

The FlashStrike is a fully mechanical, non-pyrotechnic acoustic sound grenade. Upon impact, it produces a powerful acoustic burst of approximately 115 dB, accompanied by a light flash and a brief trace of smoke. The grenade is powered by standard, easily replaceable 8-ring caps.

Is it possible to partner or collaborate with FlashStrike?

Absolutely! We actively welcome commercial partnerships with retail stores, distributors, tactical venues, airsoft teams, and content creators or influencers. To learn more, visit our B2B / Partnership section or contact us directly.
