I recently came a rood a person who wants to sell me 7.62x51 NATO tracer. How ever they claim to have removed the paint from the tips... Why I don't know. But it's imposible now to tell if this is for real. The head stamps read, IVI S0 and are double cantillured. This person claims the double canillure means it is tracer. I have two pictures of what they want to sell me as (tracer ) can anyone help me tell if they are Infact tracer with no painted tips? Sorry, I don't know how to attach images
