| Went to the range the other day to test some reloads. I went to the normal place to pick up my brass and it wasn't there, none of it was. Then I widened my search and eventually found them in front of the bench, They were ejecting at about the 2 o'clock position (the barrel being at 12). Haven't seen this before. It usually ejects at 4 o'clock. Not sure if it was the reloads or an ejector problem. I keep a spare bolt in my pistol grip and could have simply put it in to see if there was a difference, but I had to leave. Wont be able to get back to the range until next week. Anyone ever see this and what could be the problem? |

To clarify from your last sentence, this is a different gun along with different ammo than you normally shoot, or the same gun and different ammo? Yeah i knew that would be potentially confusing. The gun with the strange ejection pattern is a 5.56. But I just remembered that I shot factory loads too and they had the same strange ejection pattern. The rifle with the normal ejection pattern is a 6.8. I'm taking out that last line about the 6.8 |
| Yeah, the 5.56 with the forward brass ejection pattern is likely a symptom of being a little overgassed. Is it a carbine length gas system perhaps? Regardless, it likely just indicates that the gas system needs to be tamed with an adjustable gas block or more commonly achieved by a heavier buffer setup. Apparently your 6.8 has a good balance between the ammo your using and the gas and buffer combination in that rifle...hence, the more desired brass ejection pattern at 4 o'clock. Different brands and types of ammo can often play a large part in this ejection pattern issue, but usually one can get acceptable results with just a gas tuning device and/or a properly balanced buffer setup. If you're a serious reloader who experiments with widely different bullet weights and powder charges, an adjustable gas block might be a good investment. |

Im not sure I would go about throwing an adjustable gas block into the weapon just yet. Although they are effective, they are just another mechanical part that can fail within the rifle. The 16" CLGS is a rough system, but is one of the more common GLS due to the 16" barrel rule. My first option would be to pick up an H2 buffer and see how it changes, if any. Might "feel" a little smoother.
Is it possible to swap out your barrel and HG set up with a 16" MLGS? This might be the most efficient way to go. Probably not the cheapest, but still effective method and you can still use the old GB depending on how you're set up now. |
Hotter rounds have higher pressure. No surprise there.  So they leave the ejection port with more energy and strike the case deflector. And bounce forward to around the 2:00 position. While lighter loads will come out and back without striking the deflector and land more towards the 4:00 position.
Just your case deflector doing its job. |
