View Full Version : Ejection issue?

Hey all,

When I was out at the range Friday I noticed all my brass was being thrown out to the right and in front of the weapon. Kinda cool because I didn't have to police any brass but with my other upper all my brass was throw to about 4-5 o'clock not 1 o'clock is that an issue?

You can ignore the chart.
Different power ammo ejects at different angles.
Gas port sizes cause pressure changes and effect bolt/carrier speeds.
Action springs and buffer weights can change it too.
The only thing to be concerned with is that it does eject cleanly.
If it does than you ar all good.

5.56 and it's an AR as u can see in the pic.. I also thought about my Eotech being over the port maybe the brass is hitting that a tad I saw some markings on the edge.. It does eject clean btw no fte or ftf at all with the new upper and the old st15 lower.
