View Full Version : rounds ejecting at different directions?

06-01-2012, 11:10 AM
so i went shooting the other day with my 20 inch Armalite upper and noticed that some rounds eject at 5 oclock ( wolf ) and other brass ammo was ejecting at 1-3 oclock?

this never happens to my CMMG Piston Car Upper

any ideas?

hmm interesting. with my High standard upper, i noticed my xm193 ejecting almost straight forward at about 1 o'clock, while the PMC .223 would eject a little more outward like 3 o'clock. curious to know was well.

different power ammo will eject at different angles.
no problem here as long as it reliably ejects and feeds.
bcg speed changes with different gas pressure that the ammo genrates and you are seeing the difference.
carry on.
