So experimenting with durability of 3D printed AR lowers. 1st creation so will see how things progress during the testing and tracking phase.
2-17-18 60 of 61 .223 rounds expended this morning. The one round didn't expend due to bolt not closing fully. Think that is more a break-in period on the upper than anything. No sign of cracks or weakness. Will continue to track and monitor results.
Will have to take some video next test fire
