Full description


The 40 Mike is one of the most powerful Airsoft 40mm Gas shells ever made up to the point! Lovingly crafted by Airsoft Innovations this grenade has been specifically designed for use in Airsoft Games to make up for the shortcomings of a traditional MOSCART Grenade: this thing shoots 150 BB up to 100ft, with an impressive 10ft spread.

The Grenade is constructed from CNC machined Alloy, and features Airsoft Innovation's own 'Quantum Drive' technology, which means that every single BB will be shot from the grenade, and fire every single round at the same high power. Due to the way the grenade has also been produced the grenade is a lot safer than standard MOSCART, being able to be dropped up to 6ft without activating itself, unlike other traditional MOSCARTS which can be activated with a drop from a small height.

Worried about maintaining your Grenade, well that's not a problem, in traditional MOSCART grenades you would have to strip it down every few shots and re-lubricate, well the 40 Mike is all self contained, so you only need to make sure that you use lubricated gas to keep it running smoothly. 

Please ensure that you only use Green Gas, and Lubricated Propane to power your grenade. Do not use: Co2, HPA, NUPROL 3.0, or NUPROL 4.0 as this can damage the system due to their higher powers. If you would like to lower the FPS of your 40 Mike, then you can always use 144a Duster Gas, or NUPROL 1.0. It may be worth having some spare just in case your Gaming Site requests this.

This grenade is perfect for those Airsoft Skirmishers who love their launcher to sound like an angry duck, or for those who love the idea of finally being able to get their hands on an Airsoft MOSCART which will finally put true fear into the enemy team.
