First off, thanks for looking
 The thread title says it all. One of my shooting buddies just finished a new AR build and is borrowing one of mine. My stuff came from a local guy who has since gone out of business. Where is the best place to buy one? Thanks in advance. |

I think CDNN is selling brand new Colt bolt/carrier assys for about $100.

I second the CDNN recommendation. They have really easy online ordering too.

Mine came in today.It only took 2 days from when I ordered it.I've owned BM, DPMS and RRA bolt assemblies and all I can say is the Colt assembly I got today is in a whole other level of quality.Best $100 I ever spent.

Thanks for the replies guys. Does the CDNN version have the bolt and the carrier?
The picture on their site looks like it does, but the product description only mentions the bolt. Thanks in advance [:)] |

I looked at the CDNN assemblies, and am wondering if these Colt bolt & carriers might be seconds or rejects or fakes or such? I thought that real, genuine, new Colt parts were avaliable through only approved outlets. Is it safe to assume these are the real deal?
Thanks, as I really am wondering about this. |

That is an unbelievable price. If thats new someone ought to buy em all and make a profit in the EE over the next few months.

CDNN has a good reputation for being a decent outfit with good prices. I'm inclined to give them the benefit of the doubt until I hear otherwise. |

I too have a good opinion of CDNN, and have purchased from them in the past. Like DevL I noticed the very low price. What would be the usual going price for a true, new, Colt assembly? Let's just hope that this isn't a case of too-good-to-be-true. I'm in for one.
Will someone who has received theirs verify it against the Colt information found here: [url]www.biggerhammer.net/ar15/barrelsbolts/[/url] |

Mine is marked with a "C" on the carrier and "MPC" on the bolt.

Quoted: Mine is marked with a "C" on the carrier and "MPC" on the bolt. Sounds like the real McCoy to me [:)] And once again thanks for the heads-up on this kickass deal. I wish I had waited before I bought mine-I paid $179 each for three complete Colt bolt/carrier groups. At the time I couldn't find anything cheaper and I wanted to have a spare for every AR I owned. Oh well [:\] |

Imagine they are the carrier/bolts from these, listed on the same page.:
Colt AR-15/[b]M16[/b] SP1 Upper, New Factory BRAND NEW • Colt Factory SP1 Upper Assmebly • Tear Drop Forward Assist • Triangular Handguards • 20" Chrome Lined Barrel with Flash Hider • SP1 Sights • [b]NO BOLT!![/b] BTW - They have $20 Meprolight Tritium Front Sightposts as well, wonder how old they are. Not a bad deal since CDNN has a single cost shipping fee. Luck Alac |

Luck Alac I just ordered another bolt assembly and couldn't resist trying out those night sites for $20.I'll post how good they when my order comes in. Edited to add they have broken shell extractors real cheap for like $2.50 |

Is the firing pin more shrouded on the bottom of the carrier, similar to the new RRA's. Got a pic? Danny |

Here you go Minuteman.It's shrouded just like my enhanced RRA was.

Holy Shit! 1 more thing I've got to add to my list.
Thanks E_H and Redbone! Something strange is going on here. I can't see the url Redbone listed in his post for the pic, but after I hit reply and scroll down I can see it in red. WTF is going on there? Danny |

Is it legal for me to install a M16 Bolt&Carrier into an AR15?
That is a great price for a Colt Bolt/Carrier group. |

Quoted: Is it legal for me to install a M16 Bolt&Carrier into an AR15? That is a great price for a Colt Bolt/Carrier group. You can find arguments on both sides of this question. Me? I just played it safe w/my M16 carriers, and ground back the bottom shoulder about 1/4 inch, so they can't rip an M16 auto sear any more. Only take a few minutes, and you still have 99% of the full carrier weight, which I am convinced gives more positive functioning than the usual commercial cutaways. I also replaced all the notched hammers with M16 hammers that have the tail for the auto sear ground off; tho recently I acquired a new DPMS complete lower that had that type hammer in it.[:D] |

I've been reading a lot of posts on this subject since I asked that question.
Now I have some different questions. I have a Bushmaster upper with a 14.5" barrel on a pre-ban Oly lower. The carrier is a matte silver finish, marked with the letter [b]D[/b]. The key is parkerized. The bolt has no markings. The extractor spring has a blue plastic insert. Will a M16 bolt/carrier function better than what I have now? What's with the blue plastic insert in the extractor spring? |

Quoted: Will a M16 bolt/carrier function better than what I have now? Unless you are trying to solve a specific problem such as hammer catching on firing pin retaining pin, or trying to slow down your action some, you should probably stick with the standard bolt carrier/bolt. Unless you fully understand the differences between various bolt carriers and bolts, changes over the years, etc. You probably shouldn't go messing with the action of your not-broken, well-functioning-as-it-is rifle. Edited to add: You'll also have to check your headspace if you change bolts, so be prepared to buy a set of headspace gauges as well. What's with the blue plastic insert in the extractor spring? Although this seems like a basic question, I don't have an answer for you besides that it's SUPPOSED to indicate spring strength. Springs with black inserts supposedly have stronger springs. In practice this whole insert-as-a-marking-of-spring-power thing is BS. If you measure the spring lengths and tensions from different vendors, they all vary wildly with no rhyme or reason to them. Anyway, maybe someone else disagrees.. |

I just played it safe w/my M16 carriers, and ground back the bottom shoulder about 1/4 inch, so they can't rip an M16 auto sear any more. Just as a note. The Colt bolt carriers are hardend steel. That hardening doesn't go very deep into the metal, it's mostly the outside surfaces. When you grind back that 1/4" you are exposing unhardened steel. Now, is this a problem? Not really, that surface doesn't come in contact with anything but the autosear (and not even that anymore) and you don't have one of those because you are all good kids. [:)] I just purchased a milsurp Colt M16 Bolt Carrier & Bolt myself. I took it to a friend who does milling to have it milled back. Unfortunately the hardening is harder than the tooling, so I ended up dremmeling it back carefully. Turned out really nice, and I smoothed all the edges. After dremmelling was finished I polished the surfaces with Mother's Mag and Aluminum polish. I'm considering bluing it, but first I was going to research how that would hold up (haven't gotten around to it). I purchased this item to help solve specific problems I was having though, if your rifle works fine, you might consider spending your $99 elsewhere. |

I have problems with my current setup, and not wanting to hijack this thread, I posted over on the troubleshooting forum.

Anyway, maybe someone else disagrees.. You're exactly right. In an ideal world every manufacturer would conform to the same standards but unfortunately they don't. On my Colts the blue insert supposedly indicates a regular extractor spring, and the black insert is used in conjunction with a heavy duty copper colored extractor spring. That being said I have three non-Colt spare parts kits and each spring is clearly different, even though all three kits came from the same company. |
