How do you adjust the brass deflection on the AR15? Some of my uppers will deflect brass to the right and to the rear at a 45 degree angle which is ideal. Another upper will deflect brass to the right but, towards the front at a 45 degree angle. This makes picking up brass difficult when I'm at a range. As I have to wait for a line break before I can pick up my brass.
things effecting ejection:
speed at which the bolt/bc goes to the rear (buffer weight and spring)
I'd just enjoy that your rifle is 'healthy' and you have no other "problems"
