THE IMAGE ABOVE IS A PAID ADVERTISEMENT We had 3 successful range sessions averaging 60 per session with no issues. On the 4th session we shot another 60 rounds and had 1 stove pipe. The 5th range session we shot 200 rounds and had 3 stove pipes. Things we tried: 1) Eliminated magazines (Tried P-Mags, Thermold & C-Products). 2) Swapped carbine buffer with H-Buffer, still stove piped. 3) Tried another friends BCM BCG and the rifle worked flawlessly. Took BCG out of "problem rifle" and installed into a "problem free" 11.5 BCM upper and the "problem BCG" worked flawlessly. 
4) Stove pipes happened with Remington and Centurion. Any ideas on why this one SBR is stove piping and the other is not after these things were tried  This is confusing why the rifle worked fine for 250 rounds and is stove piping on the last few trips.
Solution: Ok, so the solution BCM decided on was to replace the entire BCG for added insurance. They believe it was an extractor issue but decided to go further with replacing the BCG so no future problems occur. Great folks all the way around. Paul sure knows how to take care of business. I was wanting to buy a Vickers mag release for my Glock and emailed him to throw in with my upper, he emailed me back and gave me the mag release free of charge. Now that's CS

That is my next plan, going to take the bolt a part tonight and check/clean it and go from there.

Maybe try putting the black o-ring that comes with the BCG in the extractor?

I was just talking to my friend about this o-ring, it is just funny his works fine without it so I was hesitant on putting it in the problem BCG. We did swap bolts between the 2 BCG and his "problem free" bolt worked fine in the suspect BCG. The one thing we did notice tonight when we took both bolts a part was his extractor was wearing evenly and the suspect bolts extractor was not wearing evenly at all, it was only wearing on one side. |

I would guess the key is to slow it down and make SURE the ejector and extractor is perfect.
You can easily replace the ejector spring with an upgraded one...good insurance. Just takes a small cheap tool from Brownells and a punch. Use the O ring on the extractor and make sure the hook is sharp like a cat's claw. Clean under the hook. With plenty of extractor tension, a good spring on the ejector/extractor, you should be good to go. You might also include an H2 or H3 buffer...never hurts to slow things down a bit. |

I am not sure buying another buffer to fix this problem should be a remedy, it should be functioning fine with either a carbine or H buffer. I am just still perplexed why this BCG is having problems and my other friends is not. |

Both parts looked to have no damage or anything out of place, it was just that the "problem" BCG extractor was only wearing on one side and not evenly like my friends BCM BCG was. |

We are only talking about an ejector w. spring and an extractor w. spring...so it really wouldn't be that big of a thing to just change it all out and go from there. It is wise to keep a few spare parts around anyway...so you might want to go to BCM or Brownells and order up a few spares. Buy quality...not crapmaster or DPMS. |

Both parts looked to have no damage or anything out of place, it was just that the "problem" BCG extractor was only wearing on one side and not evenly like my friends BCM BCG was. Uneven wear on the extractor in my mind would mean that there's not enough tension assuming nothing else looks out of place. The O-ring will provide more tension. Either way I'd be curious to know what BCM would say on the matter, they provide the O ring with the upper (not installed though) so my guess is that's what they'll say to try next. |

Hmmm... I don't have any carbean gassed guns that eject at 4 o'clock.... not that there's necessarily an issue with that. But typically a carbine... especially an SBR, will slam the brass off of the deflector and fling it in the 1-2 oclock area.

So to finalize this thread I got a call from Paul the owner of BCM this morning and he is having the upper and BCG shipped back to them for replacement of the extractor/spring and possibly the bolt for added insurance. He stated the o-ring was a band aid and not a solution to the problem I am having. He stated it would not take them more than an hour to fix the problem since he said the 11.5 should function 100% all day long. They will replace some parts and test fire it with a few mags to make sure the problem is resolved.
All I can say is after talking with Paul for about 30 min he has to be one of the nicest guys I have ever dealt with and his CS was top notch. When I emailed them it only took Paul less than 5 min to call me, that is some stellar CS right there. Anyone who ever had any preconceived notions about BCM or their CS let this thread lay them to rest. |

OP I hope you get it fixed dude Thanks for the kind words, I have faith in Paul that he will do me right. He said there is no reason it shouldn't run 100% after they get their hands on it to fix the bolt/extractor problem. |

Getting an 11.5" to run like a 16" is not as easy. The shorter barrel ARs can be finicky and may need tweaking to run 100%. Paul will fix it, he always does. |

this is in no way a crack at anything BCM nor is it a comparison to any BCM products. just making a statement on personal experience with a Bushmaster. my factory 11.5" Bushy ran like a champ. from black hills to wolf the thing was flawless. i ran it hard out of the box and can honestly say that it never let me down. there was no need to replace any of the parts (springs, o-rings, buffers, etc..). i didn't keep an accurate round count as my guns are for shooting, not to hone my math skills. i sold it for a 10.5" LMT which got sold for a 10.5" Noveske but that's all in what i wanted and not a reflection on the Bushy.
OP, i'm glad to hear that BCM is getting you all fixed up. i've never needed the BCM customer service but all of my dealings with them have been excellent. |
