Seems like I've read before about shell casings and the direction they should fly out of your AR. Basically if the weapon is timed right the casing should fly out in the direction of 2 o'clock. Is this right or am I crazy?

Please make that pie chart go away!! If your rifle ejects reliably then don't worry where the brass is going. I don't understand this statement. The AR platform exists in huge numbers precisely because there is a tight tolerance standard for every part of the gun and ammunition. So if the upper is truly spec, it has a brass deflector in the same place as all the other guns. I don't see how the chart can't be used as a guide if there are function problems. I agree that if the rifle HAS NO FUNCTION PROBLEMS then chasing down "perfect ejection" is a waste of time/money. But as a troubleshooting tool for rifles that have function issues why is it not a useful tool? |

The chart is ONLY useful if there is a problem with the gun's ejection. The angle the gun ejects at is controlled almost entirely by how "hot" the round is, so in the same gun, different loads WILL cause the gun to eject in different directions.
The chart makes it look like every round should be ejecting exactly the same, regardless of whether it's a mild .223 load or an ultra-hot 5.56 load. That's simply not mechanically possible, but people get the idea that if ONE round does something different it means their gun is broken. THAT is why the chart should go away. It's a troubleshooting aid, not a specification. |
