🔎 UNIDENTIFIED Any ideas on age or ID? It’s a bullet casing marked 5.7 x28 fnb 07?

Is a brass from a fn five seven pistol, or military equivalent(think they made some rifles for military in same caliber). Fairly new, less than 30 yrs old. If fn uses the same nomenclature as others on their brass 07 could be the year.
