I recently purchased six of these mags from CDNN and am completely satisfied (I also purchased several 17-round Browning Hi-Power magazines with that order and am equally pleased). The English mags they are selling are, in fact, "brand new," contrary to what some retailers advertise. I actually like these mags more than USGI and feel that construction quality is superior in several respects: more and cleaner weld points; flawless, proportionate steel construction; a rugged black finish (bluing?). The mags feature black followers, but they functioned flawlessly for me in a Bushmaster Dissipator. Because they are steel, they are a bit heavier than USGI (but, since I'm no longer humping some 12 fully loaded 30 rounders around at a time, no matter to me). CDNN provided me excellent customer service. Scoop them up, you won't be disappointed.
