This is the problem with a thread like this. People who don't know things, things they don't know anything about
The OEM for the platinum is VFC.
So all you should be discussing VFC vs KWA. Not E-1 vs KWA.
Anywho, I don't have many gripes about the KWA anymore since they recently addressed a few issues and fixed a couple problems. Mag's are still an issue that needs to be fixed but eh *shrug*
VFC's are the hands down, purtiest rifles you will ever see. Great quality on the inside, but the self-shimming system will need to go if you push past around 35 rps.
