308/7.62x51 AR10 Barrel 

The 7.62x51mm NATO round was originally deployed by the US Military on the M14 rifle and the M60 machine gun. The interchangeable 308 Winchester round operates at higher chamber pressures and is an extremely popular medium- and large-game hunting round due to its wide availability, and excellent ballistic and terminal characteristics. Both 7.62x51mm NATO and 308 WIN ammunition can be fired safely in our 308/7.62x51 upper assemblies.  We offer upper receivers that are compatible with both DPMS Gen 1 (LR308) and Aero Precision M5 (AR10) pattern lower receivers.  Call us if you have compatibility questions, we are happy to help.
