Airtech Studios ICS CXP-MARS PWD9 BEU Battery Extension Unit

The Airtech Studios ICS CXP-MARS PWD9 BEU Battery Extension Unit is designed to fit on PDW 9mm style AEG guns. May also fit on other ICS PDW rear buffer tubes as well. Very easy to install so you can add longer and bigger batteries in your rear stock/buffer area. 

With it installed, you can use longer 11.1v batteries in it, with extra room to spare.  This is a must have for those that want flexibility with battery space.   Can fit up to a Titan 3000 nun-chuck 11.1v.

Installation is drop-in, no tools or anything needed.  Simply pop in place to extend its buffer tube area length.  This is a must-have for any ARP9 user!

The Airtech BEU will provide you with double the amount of battery space to utilize with no modification required for the installation. The extension units are made with strong nylon that is resistant to BB impact or rough handling. A video on installation and handling is here:
