Squid Industries Double Barrell V3 is everything you love about the double barrell, but improved. This mod still provides you with 150 watts by utilizing a dual 18650 battery design. What’s new? Now, it can sit up to a 25mm atomizer. Its predecessor could only fit up to a 24mm without over hang. This mod also has other upgraded features such as: longer lasting paint, a flush top mounted screen, and an attached battery door. Simple and solid, this is the pinnacle of what makes Squid Industries a company you will be proud to own a device from.
