I have a buddy with a pmag coming in the next few days. Hopefully we can test it in several guns to see how it works including a VFC and a KA SPC CQB.

So no one has any experience with a King Arms? I'm worried about having issues with fitting. All the G&P mids I have are a very tight fit.

Any idea as to whether these fit in a King Arms m4? Also, I realize they haven't been out but a few months, but does anyone have any experience with how they have held up feeding wise over a few months of use? Springs seem to be pretty reliable?
