Compleatly wrong the eco BB's won't break in your VS tanks...Trust me i had over 20 VS tanks and marui tanks I know... I also collect and target shoot airsoft guns sure the eco bb's may brake in some airsoft guns but the tanks air gun works in a much different way where no strain ever gets put on a bb...like a gun with a blow back slide........

I been haunting VS to improve there tanks for about 5 years now and they just now are starting to put some of my ideas i been giving Steve at toyeast into the tanks.... They sill havbe not removed the Toy like jerking back that i kept telling them they had to fix since day one when there first VS tank came out..... they did improve on the new electronics wich is a good thing....and they finnaly are making a target system for the IR series another Idea i gave Steve years back when the first VS IR tanks came out....and it took all these years later and they now are producing such a product... So If it's 1/24 tanks i had over 30 or more of them i know loads about them.... Trust me the eco bb's work fine in the tanks...

If anyone should be employed by VsTankit should be me for all the info i given them over the years!
