I finished my build yesterday but for some reason the BCG is not seating fully so i cant close the upper and lower together. The BCG goes in fine on my other AR, the BCG from the other AR goes fine into this build, is just this build and BCG combined that i guess they dont like eachother.
Cerakoted Upper and Nickel Boron AR-Stoner BCG. The other bcg which is a bit dirty left trace on the walls of the upper, i guess i might need a bit of sanding to remove cerakote on those walls where the bcg slides in, im missing about 1/4" so it can fully seat. Tried pushing it and pushing it and nothing, hard as hell. |

Wish I knew. It was bought Hear.

The new charging handle I bought was to short. 
How did they manage that bit of manufacturing mayhem? |

How did they manage that bit of manufacturing mayhem? Yeah, I'm not sure I would order from there. Don't know if they are "gtg" as they say. I'm def not buying what they selling. |

i would say charge handle as well
you've eliminated BCG as you've tried another known good bcg with the problematic upper. you've tried the new bcg with the older upper and its good that eliminates both uppers and both bcgs, so i doubt your gas tube is the blame change charging handles, and see if that fixes. |

Okay let me explain the set up again and the issue because i dont think i might have explained myself as i though i was.
New build, CMMG 300 AAC BLK barrel, BCM gas block & gas tube, PSA upper, BCM CH, AR-STONER nickel boron BCG Other AR, BCM Complete Upper, BCM BCG & CH The 300AAC was cerakoted in FDE and yes it is cerakoted on the inside, not by request but care less TBH. What i have tried: The AR stoner BCG goes in fine it just doesnt click at the end to fully go into the upper receiver to allow me to close it. Tried the BCM BCG on the 300AAC and works fine. Tried the AR stoner BCG on the BCM upper and it works fine. Also the charging handles are both the same from the same place BCM MOD 3. It appears that the 300AAC doesnt like the AR-STONER BCG LOL. When i said sand it down, i meant a slight sanding of the inside where the BCG makes contact to remove the cerakote i guess but i have not done that, rather take it back to the person who did the cerakote job. |

How about fitting the new BCG to your other AR (you said it fits) put your older BCG in the new upper (you said it fits) fire off a 100 rounds through each and then try it... I think this is my best option!! They seem to work fine on the opposite rifles. |

With all the documented problems with stoner bolts I'm shocked anyone would ever even consider buying one. But then to buy one anyway and ask what the problem might be with the build when it fails is simply beyond comprehension. Throw the stoner in the trash and get a real BCG. |

Yeah well, had i known about any issues i would have waited but then again i didnt, otherwise i would have just waited for a BCM BCG, is not like i like throwing $200 dollars in the trash can just for fun!!! But thanks for the concern! |

The new bolt is probably just tight in the coated receiver. I don't see how lightly sanding the inside of the receiver could cause a problem.
The first thing I would do is to take the bolt out of the carrier and hand slide the carrier back and forth in the receiver. That way you can tell if it is dragging or tight somewhere. If you do "hone" the carrier guide rails, do it slowly and only take off enough to make the carrier move easily. |

Anyway, this site is a wealth of information, simply asking about intended purchases in this forum will net a shit load of differnt opinions and experiences with the gear in question. Often it is hard to wade through all the answers and come to a conclusion but in the case of really poor quality items the consensuses will be overwhelmingly negative making the decision clear as day. The stoner would have been in that category. Nobody likes losing money but education can be expensive. Take it as that, education. The stoner carrier should be fine, simply replace the bolt, that's the shitty part. Poorly manufactured out of inferior steel with questionable/faulty hardening. |

This is something i was researching or looking into the thread of BCGs in stock, i asked about it there and there seemed to be no problems at all at the time, dont like starting threads just for asking that simple question. Dont worry next time i will stick strictly to BCM and whatever else works from what people have to say here. I always ask and do my research, this site is definitely fantastic but i guess i missed a step there. Now moving on, why does the Stoner BCG works and sits properly in my regular AR but it doesnt on the new 300 AAC? Why does the BCM BCG works fine on both?? Im going this Sunday to the range to take the old AR and put a few hundred rounds through, i will be using the stoner in it since it seems to like that AR and see if i wear it down a little and hope that fixes the problem, if not i can try swapping bolts to see if that is the issue. Thanks again!!. |

Just came back from the range and the STONER BCG was only firing 1 round and getting stuck halfway through, had to pull on the CH each time, other than that it worked as it should i guess, after a few rounds i went back to the BCM BCG and worked flawlessly as always.
What are your thoughts?? It was lubed by the way!! |
