I have a 100 round Beta C-mag for each of my AR's and I love them, they are Compact and reliable and a perfect match to the AR15 or AR10 rifle. I have one with each of my FLC rifleman's set as part of my bug-out kit or the SHTF kit. I will always have a C-mag loaded and ready to go if need be.
So the The other day I was asking myself " why doesn't C-mag have one for the AK47? So I emailed C-mag and asked them if they are working on a C-mag for the AK platform and to my surprise they said a C-mag for the AK47 in 7.62x39 should be out some time during the first quarter of next year 2014.
So I'm looking forward to purchasing one to try out. They did not give me any info on what they are going for price Wise other then they will be available shortly after the first of the year.
