From Airsoft Innovations, the makers of the Tornado Grenade, comes the "GasCan." Not really a very innovative name (lame pun TOTALLY intended), but the product sounds genuinely useful. The GasCan is a small container that can hold the gas of your choice. The purpose is to make the gas more portable instead of either leaving the can at respawn or carrying it with you. Kind of like a gas speedloader, except it doesn't fill any faster. Allegedly, a single GasCan will fit in a flashbang pouch, while two will fit in a double M4/M16 pouch.

It recently went on sale at Airsoft GI for $50 (buy one here), which is about twice as much as buying a new pistol mag.

Here's Airsoft Innovations's fill chart:


So, what do you think about the GasCan? Is it more convenient and efficient than buying multiple mags?
