m249 box mag question

[ishkaboom]

I recently picked up an A&K m249 without a box mag for it. I do not know much about the different brands of box mags but from what I see there is A&K, CA, and MAG.

Anybody have any advice on which brand to go with and or what modifications need to be made to ensure it works properly?

Well, certainly don't get an A&K box mag. They are terrible. CA's I would assume are better, but MAG brand box mags are supposedly the best. I will be buying one of the fancy MAG 'nutsack' box mags soon. But anyway, I'll I really know is both my A&K box mags feed badly and the sound activated part doesn't work..
