I have a bandolier of Winchester 5.56 ammunition headstamped WRA 70. I think it's supposed to be 120 rounds but I have 110, 11 stripper clips of 10 each. Also has a mag feeder and an inspection note. I do not own any weapons that use 5.56. Anybody know the value of the ammo? Is there any collectibility to the vietnam era stuff, or is it just considered surplus like anything else?
