So in reading the book on my M1A it says specifically to use 7.62 Nato ammo, the local dealer gave me what appears to be 12 5rd stripper clips in a bandoleer of sorts...the clips look new and are parked. They are marked CI DAO 61 and the back of the cases are marked with DA 61 and a little symbol that looks like a + inside of a circle, which I think I read is the NATO symbol for ammo. Is this some sort of surplus? The Bandoleer that has all of the pouches is marked as NATO Ball M80 or something, but you never know if someone simply re-used the pouches etc. Either way at least I scored some stripper clips out of the deal for free.
