text: This is an FN49They came in 8mm Mauser, 7.62x51 and 30-06All use the same mag and action it is very hard to distinguish between calibers without know the country of issue or the contract. These will be problems that we will run into if a large scale situation should break out. I am not saying we should all be firearms experts but a little knowledge on all weapon platforms is a great asset during these times. You may have to depend on an unfamiliar weapon and ammo.
