Double Bell V2 Metal Gearbox

The Double Bell M4 Metal gearbox is a ready-to-drop-in gearbox for your Double Bell M4. This gearbox is of amazing quality and can be installed into a lot of different gel blasters with the correct t-piece and minor receiver mods.  These are very durable and tested boxes, as we have been running them for the last couple of years without any major issues.

Please remember to check all local laws regarding the usage and ownership of gel blasters in your particular State or Territory.

Use protective eyewear at ALL times, as the incorrect usage can lead to eye damage.

Gel blasters must be concealed during transport and used in designated areas.

Please note: This gearbox is not compatible with early model, ambidextrous, fire select receivers.
