Hey Guys -
Quick question for you all... I recently purchased a new Colt 6920 and I was installing a magpul enhanced trigger guard on it today and while I was tapping the roll pin, it broke off one of the little flanges on the receiver that the roll pin goes through. It was on the opposite side that I was tapping the roll pin in from. I have installed several of these before, and I have never seen a problem like this before. Clearly there is no way to fix this without replacing the whole lower receiver, as the piece that broke off was part of it. My questions are these... a) Has anyone had this problem before? b) I haven't even shot this rifle yet and I've only had it for a few days, do you think Colt's CS would replace my receiver under the warranty? Thanks in advance for your input. |
| We see this about once a week, if you don't support the "ears" with a block of wood you will break them right off. That being said I do not think Colt will replace the receiver under warranty because you breaking it by improperly altering it is not a manufacturing defect. |

Thanks for the input so far guys...
The good news is, is that it broke off in such a way that I was able to finishing drifting the pin through and put some red loctite on the part that broke off the receiver and the receiver itself so I'm not totally f**ked, but I wouldn't mind checking with them to see if they'll help me out. I'll give them a call tomorrow and let you know. |
| In addition to supporting the ears, it makes a big difference if you put some oil or other lube on the role pin. Better yet, Rainier Arms has a screw-on version of the enhanced trigger guard. You would think that, after all these years, someone would have thought of that sooner. |

Get a MIAD kit w/ the enhanced trigger guard as part of the front grip insert. Then glue or JB Weld the broken ear in place. Sage advice and I concur. You can still be cool and will soon forget the problem ever existed. Plus you will get some extra cool stuff. New |

This is such a common f*#kup that it should be on the list of "don'ts" in bold letters along with dropping the hammer on
an upperless lower so I doubt Colt will give you much sympathy, not that it's your fault. I read where someone unf*#ked their's with JB Weld. Sorry to hear it man.

You broke your brand new pony. 
Good thing the upper is what matters, and you can replace the lower with basically any lower on the market and be in good shape. You learned your lesson the hard way on this one. In the future, use vice grips with tape on the jaws. Safer than a hammer and punch. |

Fuck tapping those pins in. Use a plier or vice grip with tape around the end and "squeeze" it in. I don't understand why people continue to tap pins. It's not necessary. I use a pair of ViceGrips that have had the jaws dipped in Plastisol-I think Plasti-Dip is the commercial name for the stuff. It works very well and doesn't tear up the ears or the pin.

| I was just thinking that you may want to modify the title of your thread? This problem really has nothing to do with the fact that it's a Colt 6920, it could have happened with any lower. This title is just going to give more ammo to the already overwhelming number of Colt haters on here. |

The OP posted that he had supported it and it broke anyway, in addition he states that he's installed SEVERAL of these at other times with no issue. Does that make it a COLT defect? Certainly not, but your fanboy pony lovers are already posting shit like "why mess with perfection" instead of providing anything constructive so please, keep the "woe are us Colt fans" everytime something is posted that you might not like. |

Agreed. A stock Colt trigger guard is as uncomfortable as any other stock trigger guard. The Magpul trigger guard is a must have on ANY lower, IMHO. |

I was stating that this has nothing to do with the manufacturer, which it doesn't, it happens all the time with various mfrs. |

Wait, I thought fit and finish didn't matter with colts?   This has absolutely nothing to do with fit and finish. It has to due with the inherently weak part of the lower at this location. It's a flaw in the overall design of the platform IMO. It was a joke. I say install the Magpul triggerguard with JB Weld and Krylon. It happens to lots of people, will not ruine the lower. I wish all manufacturers would start forging the lowers with "built in" trigger guards. Its pretty much necessary with all the people who now build AR's rather than buying them. |

'Better yet, Rainier Arms has a screw-on version of the enhanced trigger guard. You would think that, after all these years, someone would have thought of that sooner.'
Gun designers try to avoid screws which tend to come out and get lost. For the purposes it was designed for, the original trigger guard and attachment method is adequate and dependable. I put two of these roll pins in with a hammer when building my first lowers years ago and had no breakage. Right after I did it, I realized what could have happened and broke into a sweat. I would be beside myself if I had done what the OP did. The lower is ruined IMO although obviously it can be used. BTW, how are the pins installed by manufacturers? They can't risk ruining finished lowers by beating them in. |
