I actually got a free upgrade from the cheaper version, and I was really happy. I haven't figured out how to work it yet, been when
i do that will be great. I bought a d-boys m16 mag to go with it. The mag doesnt fit well, and sometimes it falls out spilling all the bbs. BUY AN ECHO 1 M4/M16 MAG.
lots of bbs
doesnt block rds if you have one.
doesnt fit well with m16 mags of other brands
doesnt lock in well to the ks p90
complicated, and comes with no instructions
