Bite the bullet. Buy the complete gun. Stockpile ammo for it. Buy high cap mags that are pinned by rivets.
Understand something here, guys. Liberals hate ALL guns and they hate gun owners too. If they go after the AR the same way they did with the Swiss Arms or the 858...owning a functionally useless lower will be enough to get you sent to the can too.
The goat rodeo with the Swiss and the 858 May have finally taught them something: we know the liberals want to take our guns . We aren't going to give them up. How do they want to proceed?
