Reusable Mechanical Design • Spring Powered • Up to 130 BB Capacity • No Gas or Batteries • BB & Gel Ball Compatible • 4 Grenades Included

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

Add a reusable mechanical option to your airsoft loadout with the 6mmProShop GBR Airsoft Mechanical BB Shower Simulation Hand Grenade – Type B / Green / 4-Pack. Designed for organized recreational airsoft environments where reusable simulation devices are permitted, the GBR combines a spring-powered mechanical system, durable lightweight polymer construction, high BB capacity, and compatibility with both standard 6mm airsoft BBs and suitable water gel balls.

Unlike gas-powered alternatives, the 6mmProShop GBR uses a mechanical spring-powered operating system, eliminating the need for green gas, CO2, HPA, or batteries to power the mechanism. This makes the GBR particularly appealing for players looking for reusable field equipment without adding another power source to their loadout.

Each package contains four Type B Green GBR units, with each capable of holding up to approximately 130 6mm airsoft BBs. The manufacturer lists a distribution radius of approximately 5 to 8 metres, giving the GBR a distinctive BB shower effect for compatible scenario-based gameplay.

01 // MECHANICAL SPRING-POWERED DESIGN

One of the biggest advantages of the 6mmProShop GBR is its fully mechanical spring-powered system.

There’s no electronic firing circuit, battery pack, gas reservoir, or disposable CO2 cartridge required for the operating mechanism.

For regular airsoft players, this helps simplify field preparation and maintenance. Instead of keeping another battery charged or carrying additional gas specifically for the device, the GBR relies on its reusable mechanical design.

For MilSim, scenario games, and other approved airsoft environments, this provides a straightforward alternative to gas-powered simulation equipment.

02 // NO GAS OR BATTERIES REQUIRED

The GBR’s mechanical design means you don’t need:

Green Gas
CO2
HPA
Batteries

That can be a major convenience for players already managing AEG batteries, radios, optics, gas magazines, and other equipment.

Fewer power requirements also mean fewer consumables and electronic components associated with the device itself.

For players specifically searching for a reusable airsoft BB shower grenade without gas, the 6mmProShop GBR offers a purpose-built mechanical platform.

03 // UP TO 130 AIRSOFT BBS PER UNIT

Each GBR has a listed capacity of up to approximately 130 standard 6mm airsoft BBs.

With four units included in this package, that provides substantial total carrying capacity across the complete set.

The GBR is designed around a BB shower concept rather than conventional directional firing. When used appropriately within an approved game environment, the system is intended to distribute its compatible ammunition around the device.

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

04 // APPROXIMATELY 5–8 METRE DISTRIBUTION RADIUS

According to the supplied specifications, the GBR can distribute compatible ammunition across an approximate 5 to 8 metre radius.

This wide distribution pattern is one of the defining characteristics of the system and makes it suited to airsoft scenarios where reusable BB shower devices are permitted.

Because field rules surrounding simulation equipment vary significantly, always check with the game organizer before bringing this equipment onto the playing field.

The field’s rules—not simply the device’s specifications—determine how and where it may be used.

05 // COMPATIBLE WITH BBS & WATER GEL BALLS

The 6mmProShop GBR provides additional versatility by supporting two types of compatible recreational ammunition.

It can accommodate:

Standard 6mm Airsoft BBs
Compatible Water Gel Balls

This dual-ammunition design gives the GBR potential use across different recreational game formats.

Always ensure that the ammunition you’re using meets both the manufacturer’s recommendations and the requirements established by the venue.

06 // LIGHTWEIGHT POLYMER CONSTRUCTION

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

That’s an important consideration for equipment designed to be carried alongside magazines, hydration, protective equipment, radios, and other field gear.

The polymer body helps keep each unit manageable without sacrificing the reusable nature of the design.

Because reusable field equipment naturally experiences wear, each unit should be regularly inspected for cracks or damaged components before being returned to gameplay.

07 // PIN & SPOON-STYLE DESIGN

The GBR features a recognizable pin and spoon-style safety configuration, contributing to its simulation-oriented appearance.

Combined with the Green exterior, this Type B model integrates naturally into tactical and MilSim-inspired airsoft loadouts.

Despite its simulation styling, the GBR remains an airsoft-specific recreational product and should always be handled according to manufacturer instructions and field regulations.

08 // FOUR REUSABLE GRENADES INCLUDED

This listing includes:

4 × 6mmProShop GBR Type B Grenades – Green

The four-pack configuration is ideal for players who want multiple reusable units available as part of their field equipment.

It’s also convenient for teams, event loadouts, or players who would rather purchase a complete set instead of building their equipment collection one unit at a time.

FIELD USE NOTE // ALWAYS CHECK YOUR FIELD RULES

Rules surrounding reusable mechanical BB shower and simulation equipment vary between airsoft fields, events, and jurisdictions.

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

Always use appropriate field-approved eye and face protection and follow all manufacturer safety documentation.

MAINTENANCE NOTE // REUSABLE EQUIPMENT NEEDS INSPECTION

Because the GBR is designed for repeated use, inspect each unit regularly.

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

If a unit becomes cracked, damaged, or doesn’t function normally, remove it from service until it has been properly inspected.

Following manufacturer-recommended care practices can help maintain dependable operation and extend the useful service life of the equipment.
