I have my AR set up on a bipod where the 30 round PMAGs are too long making it just a little unstable. So I'm looking to trade for 20 rounders. The 30 rounders I have are almost brand new. I've used them only once. Also, they have the window. I'm looking for three 20 rounders in exhange for my two 30 rounders. Seems fair to me... 60 rounds for 60 rounds plus you get the windows. Willing to meet up just about anywhere on the West Side (Hillsboro, Beaverton, Tigard, Sherwood, Tualatin, etc.).
