I got a box of 10,000 Ultrasonic .12g polished BBs to go with my spring Walther P99 for Christmas. So far, the only thing that's broken is the flash hider, which broke when I had the mock silencer attached.
What I'm asking is, are they a good brand to use with the AEGs and other weapons? I noticed they have a line that goes around the outside of the BB, and an air bubble on the inside (they're clear green, polished BBs). I'd like to know, so I can buy a different brand if/when I get a new rifle, if I need to.
