This covers the vast majority of lowers, but there are some exceptions so if you have any questions, contact our support team at 866.706.0633 or [email protected].

The 308 Winchester Upper Receiver uses the standard 308 WIN Bolt Carrier Group (BCG) and the standard 308 WIN / 7.62x51 NATO Magazine. So, swap out the Upper and load 308 Winchester ammo and you are ready to go.
