MOS Manufacturing, the company behind Arcturus, are following up the release of their AK-12 AEG with an ETU version, sending a prototype for USAirsoft to check out if it is an improvement over the first version... "I don't get the chance to take a look at prototypes everyday but when a company like Arcturus trusts me to handle one, I take that opportunity.

Arcturus wants to be the best option for AKs so this is a great step forward. Want to know why? Just watch."
