Finally got the taccom bcg in to complete this 22 build. It's a taccom 22rf upper and their m4 profile barrel. I don't know if I've been hit with a case of stupidity or wtf but this bcg does not fit. The carrier bottoms out on the barrel collar with a half inch or more protruding from the rear of the receiver.
I have no experience with 22 ARs or their respective parts so maybe I'm overlooking something that would be obvious otherwise. Any help would be greatly appreciated, thought I'd be able to throw the bcg in and test fire the damn thing. |

Spread the "cheeks" of your extractor so that it fits over the barrel collar... The carrier? I figured it had to fit with the barrel collar but I am not seeing anyway it'll fit no matter how much I spread it. The left side of the collar doesn't have enough room for the piece to fit between it and the wall of the receiver |

Thanks for the help. I just sent them an email. Pretty disappointed right now. Was excited to get this completed for my wife but looks like I'll be waiting even longer Quoted:

OK.....well, first off, let verify that there IS a firing pin in there. :)
NExt.....you'll want to push on the back end of the firing pin and see if the front end of the pin extends out to within .020" of the very front of the bolt. Basically.....it should be sticking out from the base about 1/2 to 2/3's of that step Tim |

It is possible that you have too many shims installed. Any way you can pull the firing pin out and see what is stacked on the back side?
You will have to disassemble your BCG then drive the firing pin roll pin out. The pin will slide out the back. There might be some really small shims on it that prevent the pin from sticking out too much. It looks like you might have one too many installed. MAHA |

Do you have any high velocity handy? Sometimes a break in period is required... Quoted:

Yep, I've got 3 different bulk bricks. 2 different federal and a Winchester. Tried a few of a different brand as well and still nothing. I wondered about that as well. I don't have any high velocity right now but could probably get some. Best "quality" I have right now I assume would be the federal "target" ammo |

Do you use this lower on anyhting else? Is this the first upper you have tried to shoot with the lower? Can you post a photo of the hammer/trigger in the lower. MAHA I tried the upper on a lower with a mil spec cmmg lpk and a lower with a Cmc 3.5 trigger. No go on any of them. I'll post a pic when I get home. I built the lower specifically for this upper so I haven't shot it with any other uppers. The hammer does look smaller than some of the other milspec triggers I've put in lowers but even the "normal" one in the other lower didn't fire it. Really appreciate all the responses/assistance |
