Too bad you can't print barrels......
Because you just torched the rifling right outta the first few inches of that one. As for testing a Lower, firing it puts no stress on it. How about seeing how many times you can put in and take out the pistol grip screw, the take-down pins and the buffer assembly? That'd be more relevant to testing its strength. |

The first lower they test fired lasted 6 rounds before the section that holds the buffer tube snapped off. Test firing does stress the lower.

You can get one for the pre-panic price of a DD rifle, ~$1200.

Wait, you guys actually used that 3D printing technology that to make this? That's wild! I thought the original designers were having some big dispute with people aboutusing their product to make weapons. Just imagine in the future the weapons anyone will be able to print.
