If you're looking for some good low capacity mags for your AR, avoid these "5/9rd Combo Magazines" that CDNN is selling by all means. I ordered one and upon inspection the thing wouldn't even fit into the magazine well because the dimensions were so off. And they appear to be coated with some cheap grey spray paint that rubs off. I even emailed CDNN before ordering to see where they were made and got the reply, "They're made by a contractor for us, and they work GREAT! We've sold 1000's"
Yeah, sure. Funny how my emails went unanswered all of a sudden when I complained. I'm sure these are being made in the same place that rubber chickens and fake dog $hit come from. Also, when sending it back they sunk so low as to make me cover the shipping cost even though it was faulty merchandise on arrival. Great policy. I'm pretty sure I've seen these being sold a few other places as well like Midway, advertised as "John Masen" magazine, so beware. Save your money and go for some quality ones from Armalite or Bushmaster.
