Hey there Coprs,
I'm actually having a few issues with these mags and my VFC KAC PDW. The mags definitely fit in the magwell (with a fair amount of wobble actually) but they can easily be ripped out without using the mag-catch...
To be honest, I'm a little ###### off since I was really looking forward to a viable alternative to the flimsy VFC mags.
You wouldn't have any tips by any chance as you've mentionned that they fit and feed nicely in this specific gun?
Cheers
