While some of our blank holders may be technically cross-compatible—for example, a 12-gauge base fitting a .209 device—we neither sell nor recommend the use of components across different calibres. This policy ensures full compliance with international safety standards and legal regulations. All Pulse Armaments products undergo individual testing and certification. In accordance with the Gun Barrel Proof Act 1968, all barrels and blank-firing components must be properly proofed prior to sale or use. This legal requirement guarantees the safety, performance, and structural integrity of every device we manufacture. For your safety and to ensure compliance with applicable laws, please use components only as designed and intended. Legal Excerpt: "A Small Arm shall not be sold or exchanged, or be attempted to be sold or exchanged,...unless and until the Barrel or every Barrel thereof has been duly proved at the Proof House..." — The Gun Barrel Proof Act 1968 (condensed for brevity)

Yes, we ship worldwide! We have agreements for sending our products with UPS. Our products are licence and certification free and therefore can be airfreighted without trouble. They contain zero stored energy and therefore pose no risk during shipping and are not classed as dangerous goods. Please note: the only products that cannot be shipped internationally (outside the United Kingdom) are pyrotechnics and blanks.

Yes, the B1 will function reliably on any surface. As it does not require impact force to detonate, it operates consistently on grass, mud, concrete, wood, and other types of terrain.

The B1 uses .209 shotgun primers and produces a sound level below 110 dB, making it suitable for use at most airsoft sites throughout the United Kingdom. However, we recommend checking with your local site or event organiser to ensure compliance with their specific noise regulations.

Our variable timing system is a proprietary technology that allows you to adjust the delay on your device with precision. There are no fixed click positions—just smooth, continuous adjustment from zero seconds upwards, giving you complete control over timing to suit your scenario.

In the unlikely event that your order arrives damaged, faulty, or with missing items, please contact us as soon as possible to report the issue. If appropriate, a replacement product will be sent to you. Please note that a replacement will only be dispatched once we have received the original item and confirmed the fault through inspection.

We strongly recommend recording the unique serial number of your B1 grenade upon purchase. If the device is lost during gameplay, report the loss—along with the serial number—to the field or site where it was last used. This information may help staff identify and return the device if it’s found.

We aim to provide cost-effective repair solutions for our customers, even for products that are outside their warranty or product lifetime. In many cases, we may request that the item be returned to us for assessment. This enables our team to accurately diagnose the issue and ensure that all components are repaired or replaced correctly for optimal performance. If you have a damaged product, please contact us to begin the repair process.

At Pulse Armaments, we’re committed to producing the highest-performing airsoft BFGs on the market. Each B1 grenade is meticulously hand-built by our skilled team using premium materials to ensure exceptional reliability, performance, and durability. This level of craftsmanship and attention to detail naturally comes at a higher cost—but we believe the result speaks for itself.
