That's not exactly accurate, The echo1 M203's are oem'd by the same company. Their external parts do break easier than a more expensive brand such as CA, King Arms, etc. Plus they are not as compatible with certain Shells. The echo or Dboys love Madbull shells, but do not work at all with CAW or pro arms shells. Hope that helps.
