Controversial take here but could it be the mags folded because they were largely rubbish?

I didn’t buy many, so feel free to shoot me down, but when I did buy them they always had the same articles. A review or two of some umarex offering (let’s be honest the pistols are all the same and so were the reviews). Some bloke in camo wittering on about how he shot a rabbit, even less interesting than listening to your mate describe a night out you weren’t on. More reviews all of which say whatever is being reviewed is good and none of which were as informative as what you can find on YouTube in two minutes. Maybe a letter or two from Walter Mitty. And possibly one interesting article that’s not worth £3:99 or whatever they went up to.

Tbh far from the ads being a problem the ads were often the best bit.
