I have several AR10 magazines which are in excellent condition. They are the aluminium waffle type with no space between the two words on the magazine floor plate. My question is how much are they worth? When I last posted two of them for sale for $200, they were sold within 3 minutes of posting the ad! I'm wondering if I put to low of a price on them. Also, I have what I think is a rare item - an original magazine loader for the AR10 mags. Could some one advise me of fair prices to ask for these items? Thanks. Bill
