I have 4 20 round (5.56 x 45) magazines for your AR15.
They come with Magpul Ranger Plates installed, standard bottom plates and dust covers are included.
They are in near perfect condition, I can't even remember if I used them at all.
I'm asking $40 paypalled and shipped to anywhere in the US.
You can also come and pick them up if you want.
I live in Dyer IN 46311.
