I searched the forum and nothing jumped out as useful.
With the cyma and KA versions of the 556 I am wondering what works and doesn't work for compatibility with Mags. Looking for first hand "I did this and it worked/didn't work."
From the link below is looks like MAG brand are the right fit for the KA but any confirmations?
Did some googling and the better of the links I could find
