Since I no longer have a H&K MP5 A5, I'm getting rid of any of its accessories. I have 2 - 25-round magazines that will work with the H&K MP5 A5 & H&K MP5 SD.
These magazines go for $29.99 online, when they are in stock. I'm willing to let these two go for $15 each + shipping (total:$30 + shipping).
Wanted to add that after a month on being listed on here solely, I have now listed these mags on a different forum as well, link. First Come, First Serve.
