It looks like the rims are getting pulled HARD by the extractor - which suggests that extraction is occurring before the chamber pressure has dropped sufficiently.
What buffer weight are you using? I'm thinking if you have a regular carbine buffer that maybe you might want to try an H2 to slow extraction enough for the chamber pressure to drop off a little more.. |

Phase 5 Tactical buffer assembly, i believe, comes with a regular carbine buffer. Defiantly, give a heavier buffer a try.

Wondering if a pigtail gas tube would help it? Just a thought, I have one on my 7.5 inch. In theory anyway, it should slow the lock time just a bit (been debated here, but I remain convinced with a steady speed it still takes the gas longer to reach the key if traveling farther).
Anyway, Phase 5 sells them, and ONLY for 7.5 inch. |

had the same problem with a 14.5 middy. Added an H buffer to it and it fixed it right up

Thank you guys!
I'm running the phase 5 buffer assembly. Which as stated I believe is standard buffer. So you do believe a heavier buffer will fix the problem. Any links to some you all would suggest? Thanks again like I said first build and still new here. Appreciate all the help. |

I went with the Spike's Tactical T2 heavy buffer - which is available from AIM (a supporter of this site) and is in stock AND ships for FREE! http://www.aimsurplus.com/product.aspx?item=XSTSLA00T2&name=Spikes+Tactical+ST-T2+Heavy+Buffer&search=buffer They also sell the Spike's T3 if you want to go that heavy.. |

Then again, I've heard of guys running 7 inchers with no special parts without trouble. And others who have loads of trouble after trying all the obvious fixes. I think these shorties can just be a temperamental lot. |

I used similer phase5 parts in my first build as well,but i used a JP Enterprises Silent Captured Recoil Buffer Spring
But i to have the pigtail buffer and have had no issues with my pistol. Not sure if this is helpful. |

With a gas block that accessible, I wonder what the pistol experts think about an adjustable gas block. You can at least dial it in better than a buffer that may or may not make a difference.

That's a slick and handy looking AR, rsxscrazy. I hope you get the gremlins out of it soon.
May I ask, what is the OAL? |

Hopefully he'll still answer, but I should be able to get you very close (I have the same buffer assembly and KX3 on a 7.5 inch barrel). Could of course be subtle differences in barrel length, or depth of threaded parts etc, but mine is 23 5/8 inches long. |

Thanks for the measurements, guys. I'm pleasantly surprised at the lengths, I thought the pigs would have added much more.
Do you like the pigs? |

I can tell slight noise dampening to the shooter. and if i can get my kinks worked out im sure it will function and does everything its advertised for, Also it looks kickass.

i got the spikes t2 buffer and it helped a ton. ejection now shoots out pretty decent other than just falling at my feet.
1.2 OZ difference in weight. surprising little difference made a big difference. http://i891.photobucket.com/albums/ac112/jones424/photo1_zps40a637d7.jpg http://i891.photobucket.com/albums/ac112/jones424/photo2_zps040457a4.jpg |

Yep, I run a H3 buffer in my 7.5, it ejects at 3:00 with steel case, and I've never had a failure of any kind with it.

The reason why the Spike's T2 buffer works is not because of the weight, but because of what makes up that weight. Instead of large tungsten or other large chunks of metal in there, it's a powder that really goes far at deadening the force from the bolt. It made all the difference for me in an ar pistol but also a 9mm ar carbine.
