Yes, you CAN fire 7.62 x 51 as well. Info below. The 7.62x51 NATO and the .308 Winchester are two popular rifle cartridges that have similar external dimensions, but differ in their internal dimensions and the pressure they generate: External dimensions: The two cartridges have the same external dimensions. Internal dimensions: The 7.62x51 has thicker walls and a slightly longer chamber than the .308 Winchester. This means that the 7.62x51 has less space for powder than the .308 Winchester. Pressure: The .308 Winchester generates more pressure than the 7.62x51. Interchangeability: A 7.62x51 cartridge can be fired from any rifle chambered in .308 Winchester, but the .308 Winchester should not be fired in a 7.62x51 rifle. The .308 Winchester's thinner brass case might rupture in the 7.62x51's longer chamber. Origin: The 7.62x51 was developed using the .308 Winchester as its "parent" case.

Hi Dean and welcome. This Barrel is stamped .308 and will fire the lower pressure 7.62 x 51 ammunition no issue. It is the opposite for .223 and 5.56 with 5.56 being the higher-pressure round. Cheers, stay safe and enjoy!

yes .308 rifles can fire the lower pressure 7.62 nato rounds but you cant fire a .308 in a 7.62 nato gun
