Aftermarket electric drum mags typically have been poor performers from what I've heard. Usually the best ones come with a gun made by the same manufacturer, ie. TOP or CA M249. However I have to say that mag looks to be of some excellent build quality, and authentically detailed. Let's hope it works.
I like that it's styled after the Soviet 75-rounder rather than the commercial Chinese pattern. This may be just the excuse I need to purchase a Guarder RPK kit!
