Without getting too crazy I would try to track down the problem keeping the same parts for both rifles. Swap the lowers from one to the other. If you have no change, then swap the BCG's (technically you should check your headspace when doing this). If the problem is still there, then you may need to look into gas ports or tubes for obstruction.

The "correct" answer here is that if the gun runs reliably, who cares where the brass lands. But this a puzzle for you, so I won't stop at that.
How new is the 5:00 gun? Is it well lubed? I would guess that it is newer than the other one, in which case it is probably just not fully broken in yet. Ant the first rule of troubleshooting is to change only one thing at a time. If you change more, you win't know what's causing what. Go back to square one, and fire a few hundred rounds, then see where the empties land. |

Thanks for the input so far. Actually, the one I'm concerned about is the older one. I have a new, spare Spike's bolt/carrier group that I can try at the next range session. If it is undergassed and ejects at 5 o'clock with .556 ammo, I'm concerned about it short stroking with .223, hence the concern. I'll also try some .223 the next time out.

Ejection Patterns
Never noticed. Spent brass goes away so gun can run. I never can find them all so I finally gave up and just leave when I'm done shooting. I don't reload anyway and the 'recyclers' won't take shot brass. If it bothers you get a brass catcher. Then you don't have to fret about it. |

Thanks WK, mine is ejecting about 1:30 which makes it hard to consistantly use my detachable brass catcher its clear mine gun is over gassed, but usign standard carbine buffer so I am going to switch to an H2 and see what happens. |

Actually you should be concerned about the one that ejects at 1 o'clock, not the one that ejects at 5 o'clock. The 5 o'clock rifle is not undergassed and will eject your .223 brass perfectly OK without short stroking. |

As I said in my OP, I got the one that was ejecting at 1 o'clock to eject at 3 o'clock by installing an H3 buffer and an extra power spring. |

Unless it is a lefty Stag the brass should land somewhere to your right, every time you pull the trigger. Other than that, don't worry about it. The location they hit will vary between loads, some ammo from one maker will go forward a bit, some will go back a bit. The chart is BS, every ammo maker I know of makes more than one load type, and the brass from each load goes a different place.

Funny, all my years of shooting this platform, and now we have a diagram with "ejector" patterns that gives all the new shooters another thing to worry about... I guess I have been too busy with concentrating on my trigger press and my sight alignment to know where my brass is ejecting to.

I've been shooting AR-15's for 25 years. I've owned 4 Colts, 3 Bushmasters, 3 RRAs, 2 Stags and 2 Spikes. This Spike's is the only one that has ejected at 5 o'clock. |

The only way to know for sure is to shoot some low powered steel cased ammo or PMC bronze or something like that. I was worried one of my rifles wouldn't cycle the weaker stuff since it was ejecting at 4 o'clock or so but it shoots it all fine.
My suggestion: Buy a box of wolf, tula, silver/brown bear, and pmc bronze and test each type.  |

Its hard to tune the ejection pattern of the AR but you wont know if it will handle lighter loads reliably until you shoot em.I use a 9mm buffer and wolf Xpower recoil spring and a BCM extractor spring with regualr black insert and I get 3 to 4 oclock ejection wether brass or steel cased.You could always try tuning the ejector spring maybe take off a couple of coils...I wouldnt do that on a rifle I was gonna bet my life on but for a bolt just used on the range I would if thst what you need.Ive seen high power shooters using M1s and M1As use a lower power ejector spring to put spent brass in a nice neat pile ejecting forward like at 1 to 2 oclock forward of the rifle.

I have 2 carbines
LMT Defender 2000 14.5 over 3000rds Home built Bushmaster lower with a LMT 14.5 uppers over 2000 one spits them out a 1pm on the table The other one spits brass out behind my shoulder Both carbines have been flawless |

I had a Bushmaster 20inch rifle that would put the brass in one small pile. To bad I don't reload for 223rem/5.56mm it would made policing brass much easier |

It sounds like you have played with the buffer weight and the buffer spring and see how that effects eject pattern. The ejector well have some effect. Play with the ejector spring to fine tune it. I like me guns to spit it at between 2 and 4 o'clock, easier to pick up BEHIND the firing line. |

OK well it turns out I actually have the H2 buffer and a M-16 BCG in the gun, and I still at the 1:30 mark..... I am about to swap out the single rail GB for an A2 FS assembly if that doesnt improve my ejection pattern what is next that I can do to improve ejection pattern  H3 buffer or one of the pistol caliber buffers or maybe a slash buffer (I have one for my .308AR RIFLE length build)
