Spoonless Tripwire Core for Thunder B – Hakkotsu

Hakkotsu Thunder B replacement core in the Tripwire version, without a spoon: it is triggered by the trip wire and turns the sound grenade into a booby trap. It works with all Thunder B shells and with Specna Arms Vapor kits, and it can also be used in place of the standard core.

Features and technical specifications

• Manufacturer: Hakkotsu
• Manufacturer code: TBH2
• Type: spoonless (Un-Spoon) replacement core, wire triggered

How it works

The 12 g CO2 cartridge stays sealed in the aluminium tube until the safety is pulled: the core then releases the gas into the shell until it bursts, with the classic Thunder B bang. With no spoon, activation comes through the trip wire, which is pulled taut to set the trap.

In the field

It is the spare for anyone who wants to set traps along paths, on doors or inside buildings during CQB and MilSim games, or simply to keep an extra core ready. It screws onto all Thunder B shells and works with Specna Arms Vapor kits, so it fits in with the grenades you already have.

Warning: use only during airsoft activities, with suitable protective equipment and in accordance with field rules.
