Gargoyle hit the nail on the head.
Big difference between milspec and USGI. Funny thing is, I see them used, rusted and beat to shit for $35 each at gunshops
I've bought three batches of 12-15. They are not refinished, they are brand spankin new, altho some of the latest(couple of months ago) have parkerized followers, I've never seen that before. Some might have a spot or two of surface rust............so what? They could be 30-40 years old. I have noticed every time I've reordered, it's taken Armalite a little longer to process the order. Makes me wonder if they have to bring them in from another location.
Bottom line, they are the real deal, all different manufactures, but if you check with Fulton Armory, markings are all correct, you will not find a better deal for the real deal. If for any reason you are not happy, Armalite will make it right. I read that right here.
Leave me a few more, I'm going to let Lou at LRB build me one....well ok, maybe two more, then I'm done....I promise....yeah right
