6MMPROSHOP GBR // TYPE B // BLUE // 4-PACK // MECHANICAL BB SHOWER // REUSABLE // 130 BB CAPACITY

Bring reusable mechanical simulation equipment to compatible airsoft games with the 6mmProShop GBR Airsoft Mechanical BB Shower Simulation Hand Grenade – Type B / Blue / 4-Pack. Designed for organized recreational airsoft environments where this type of equipment is permitted, the GBR combines a spring-powered mechanical system, lightweight polymer construction, reusable design, and compatibility with both 6mm airsoft BBs and suitable water gel balls.

Unlike gas-powered or electronic alternatives, the GBR operates using a mechanical spring-powered system, meaning it doesn’t require green gas, CO2, disposable cartridges, or batteries for its operating mechanism. That makes it an interesting option for players looking for a straightforward reusable platform without another power source to manage.

Each package contains four Type B Blue grenades, allowing players to build a complete compatible field setup from a single package. With capacity for up to approximately 130 6mm airsoft BBs per unit and a manufacturer-listed distribution radius of approximately 5–8 metres, the GBR is designed specifically for scenario-based recreational airsoft use.

01 // MECHANICAL SPRING-POWERED SYSTEM

One of the GBR’s defining characteristics is its fully mechanical spring-powered design.

There are no batteries to charge and no gas reservoir required to power the operating mechanism.

For players already carrying AEG batteries, gas magazines, radios, optics, and other equipment, reducing the number of additional power sources needed for field accessories can simplify a loadout.

The mechanical design also makes the GBR a reusable platform when properly maintained and operated according to manufacturer and field guidelines.

02 // NO GAS OR BATTERIES REQUIRED

The GBR doesn’t rely on green gas, CO2, HPA, or batteries for its mechanical operation.

This makes it significantly different from many gas-powered airsoft simulation devices.

There’s no electronic firing circuit or battery pack to maintain, and the player doesn’t need to manage a separate gas supply specifically for the device.

Its straightforward mechanical design is one of the biggest attractions for players looking for reusable airsoft simulation equipment.

03 // UP TO 130 AIRSOFT BB CAPACITY

Each 6mmProShop GBR can hold up to approximately 130 standard 6mm airsoft BBs.

This gives the compact unit substantial ammunition capacity for its size.

The manufacturer describes the system as producing a BB shower effect around the device, making it suitable for compatible scenario-based gameplay where this style of reusable equipment is specifically permitted.

Always follow the rules established by your airsoft field or event organizer regarding how BB shower devices are treated during gameplay.

04 // BB & WATER GEL BALL COMPATIBILITY

The GBR offers additional versatility through compatibility with more than one type of recreational ammunition.

It can accommodate:

Standard 6mm Airsoft BBs
Compatible Water Gel Balls

This makes the system useful for players participating in different organized recreational game formats.

Ammunition should always meet the manufacturer’s recommendations and the requirements of the venue where the equipment is being used.

05 // 5–8 METRE DISTRIBUTION RADIUS

According to the supplied manufacturer specifications, the GBR is designed to distribute compatible ammunition across a radius of approximately 5 to 8 metres.

Actual results can vary depending on ammunition type, surface conditions, maintenance, environmental conditions, and other variables.

Because of this distribution pattern, players should always use the GBR only in approved areas and according to the safety and gameplay rules established by the field.

Never assume that a particular airsoft venue allows mechanical simulation devices simply because conventional airsoft replicas are permitted.

06 // LIGHTWEIGHT POLYMER CONSTRUCTION

6mmProShop manufactures the GBR using lightweight and durable polymer construction.

This helps keep individual units manageable when carried as part of a larger tactical loadout.

For players carrying several magazines and other field equipment, minimizing unnecessary equipment weight can make a noticeable difference over a full day of gameplay.

Polymer construction also gives the reusable GBR a practical balance between durability and portability.

As with any reusable field accessory, inspect each unit regularly and remove damaged equipment from service.

07 // PIN & SPOON-STYLE APPEARANCE

The GBR uses a recognizable pin and spoon-style safety design, giving it a traditional simulation-grenade appearance suited to MilSim and tactical airsoft loadouts.

The design provides the visual styling many players look for when building a cohesive kit while remaining an airsoft-specific recreational product.

This Type B version comes in Blue, giving the units a distinctive appearance and making them easier to visually identify among other equipment.

08 // FOUR GRENADES INCLUDED

This listing isn’t for a single GBR.

PACKAGE INCLUDES: 4 × TYPE B BLUE GBR GRENADES

The four-pack format makes it useful for players who want several reusable units available within their field equipment.

It can also be practical for teams building compatible scenario equipment or players who simply prefer having multiple units available rather than relying on a single reusable accessory.

FIELD USE NOTE // VERIFY YOUR FIELD RULES

Airsoft fields and events can have very different rules concerning reusable mechanical BB shower and simulation devices.

Before bringing the 6mmProShop GBR into gameplay, confirm that your venue permits this category of equipment and understand how it is treated within that field’s elimination and safety rules.

Always use appropriate field-approved eye and face protection and follow the manufacturer’s safety documentation.

MAINTENANCE NOTE // INSPECT REUSABLE EQUIPMENT

Reusable mechanical equipment should be periodically inspected for signs of wear.

Check the polymer body, safety components, mechanical system, and other accessible parts for visible damage before gameplay.

If a unit becomes cracked, damaged, or doesn’t operate normally, remove it from service until it can be properly inspected.

Keeping the mechanism clean and following manufacturer-recommended maintenance practices will help preserve dependable operation.
