Fuck that chart. If it feeds, shoots and extracts reliably when it’s clean and dirty then shoot it and be happy. |

A heavy buffer will help. Or put an adjustable block in it.

Might be your recoil buffer spring. Had the same problem on an ar pistol I bought. Added a spikes tactical heavier buffer. Turns out my spring was short a number of coils. Replaced the spring, problem solved.

Quote HistoryQuoted: Why do you believe this is a problem that needs to be solved? There is no need to start swapping parts if the rifle is otherwise flawless. Next post after tinkering with springs and buffers will be “my gun short strokes and fails to feed”. Which obviously means the next step is enlarge your gas port. Satire of course, but if it’s running fine, why mess with it over something as subjective as “ejection pattern“? |

My rifles throw the brass across the sun dial....the LMTs are the worst, but never had an issue with them. My SR25 seems to behave the best, it makes neat little piles right at 3:55....but what is best as long as the rifle is working. Every one of my LMTs spit brass at 1:30 regardless of what I do to them...I dont try to change them anymore.
I used to get all worked on where the brass is clocking, but got over that real quick.... |

I'd run an H2 and then let the brass fall where they may. Might even add a Sprinco "blue".

Having more powerful ammo ejecting in a 1-2 o'clock pattern means your lower power ammo, like commercial .223 will also eject successfully in a more 3-6 o'clock manner. Means it will run more reliably with varying ammo.
If you really insist on changing the ejection pattern, heavier H1 or H2 buffer and/or extra power springs. Or get an adjustable gas block. I'd recommend the adjustable gas block since you will be able to change the port size depending on ammo your are shooting. |

Well, you state that it's run flawless but are asking how to fix a preceived problem. You don't have a problem, you've just read too much on the internet.
My M&P like many others, is slightly over gassed. So it will run pretty much any ammo I stick in a mag. No problems with it in 10 years. Not sure what you think S&W is going to do for you when your rifle is functioning as designed. |

There's nothing wrong with the gun. 16" factory guns with carbine gas (what gas system yours has) will always be "over gassed", which it's not, because if it was it wouldn't run. |

Quote HistoryQuoted: I think I will call Smith & Wesson. I am sure they will be friendlier than the assholes that responded to my post! With no useful information. You got useful information. You got "your gun is fine so carry on." Or "add a heavier buffer". What do you think S&W is gonna say? The folks in here know what they are talking about. The ejection pattern is not really important if you're running 100%. If anything it can help you tune your rifle. 1 or 2 o'clock suggests it's slightly over-gassed. Try an H2 or H3 and see how it runs. But over-gassing isn't really an issue unless you want it to be. Being under-gassed would be an issue. |

There is no guaranteed fix for ejection pattern. What I would do is install an H2 buffer, Sprinco blue and sprinco 5 coil extractor spring. If S&W is still running semi auto bcg, you could throw a full auto carrier in there to help.
Ejection direction/pattern really isn’t a big deal, and does not mean your rifle has an issue. My ARs setup like what I recommend above, they throw them consistently in a nice pile, usually in the 3-4 range. I would bet that S&W is running light carbine buffer and spring, and they are going to tell you it’s fine. It can be better. |

Not trying to be sarcastic here, but why does it matter where the heck it puts the brass?
I forget that’s even a thing until I see these threads. My 16” carbines seem to put brass around the 2 o’clock area. They function just fine with everything from shitty steel case ammo to 77gr mk’s with 24.3 grains of tac Hell, I loaded some very week rounds that wouldn’t even cycle my 20” rifles and they still ejected them. Wouldn’t hold bolt open on last shot, but still cycled. Sounds to me that your rifle indeed does run flawlessly. Don’t fix what’s not broke. And dents on brass from shell deflector means you deflector is doing exactly what it’s supposed to do. Deflecting brass. |

I changed ammo from .223 Wolf Gold to 5.56 IMI recently, and the recoil felt much stronger in one of my carbines. So I started watching videos and heard all the recommendations about changing buffer weights etc. etc.
Since my AR has never misfired even though it was throwing cases at 2:00 or so, I went with changing the buffer spring to a Sprinco blue spring. It did make a slight difference in felt recoil, and was fairly inexpensive to do. I couldn't tell that spring change made any difference in where the cases were thrown. That is all I am going to do with mine as long as it functions properly. I will tell you the members who posted in this thread are way more knowledgeable about AR's then I am, and I consider their posts very useful information. I hope you are able to satisfy your concern OP. |

As suggested by some posters, install H2 buffer and Sprinco blue spring. https://www.sprinco.com/ar-buffer.html If this does not help, then use milder ammo like 223 Remington. When my rifles, Noveske (hammer forged middy) and Armalite (middy) dented brass in the middle and throwing it forward, I did not bother asking for advice here, because I knew the responses I would get like "fuck that chart" and so on. I installed heavier buffers and recoil springs. Photo of Noveske spent brass. Of course the rifle went bang and ejected.  Attached FileIn Armalite middy, I use H3 buffer and much heavier recoil spring than blue sprinco. Pretty lame solution for this overgassed POS 4140 barrel. The upper shows no wear whatsoever after 3460 rounds, therefore I will replace the barrel with Daniel Defense or FN (hammer forged ones). Below, LMT spent brass. I did not like it at all, although it went bang and ejected. Therefore, I replaced this lemon upper with new one from Rainier Arms. This was years ago.  Attached File Attached FileThe only rifles I have no issues whatsoever are my 3 Colts LE6920. Perfect finish, function and reliability. |
