If you are going to purchase an enhanced RRA bolt carrier group I would suggest you purchase it from EAGLE ARMS.... $95 for a complete enhanced RRA bolt carrier group.
This is how EAGLE ARMS describes RRA's Enhanced Bolt Group: RRA "Enhanced" Bolt/Carrier Assy Complete with firing pin, gas key, etc...everything you need to install and use immediately. Factory assembled with a chrome-lined bore and gas key. ("Enhanced" means that the normally machined out open area under the firing pin is left intact (see pic above, enhanced carrier is on top of original style). This provides a fully supported firing pin assembly and a much stronger carrier. The enhanced carrier also has more surface area on the rear lower edge for a little added mass. The lower rear edge is slightly longer than the standard AR15 carrier, but not as long as the M16 unit). This is the best bolt/carrier available for this price. $95.00 SALE Learn more about it here: EAGLE ARMS

"Much stronger bolt carrier" -- maybe. But the bolt carrier needs no great strength in this area and is only made of steel to give it mass and handle the gas pressures.
The cut out on the bottom of the AR15 bolt carrier is designed so the hammer can catch the firing pin in the event of disconnector failure and prevent a runaway gun. The "enhanced" carrier seems harmless enough, but there's no need to replace a working, standard carrier with it. -- Chuck |

weird how my "enhanced" has more metal around the firing pin than above pic.
*edit* infact all u can see of the firing pin is the end like this.  pic off eagle fire arms shows the difference. |

Wasn't this done to reduce slam firing?

If you meant to reduce the occurance of the free floating firing pin setting a round off then no. If you mean to stop doubling with a ruined disconnector then yes. In so stoping it it also locks the rigfle up... a bad thing.

Thanks for the information.
But just one more question. How good is this bolt carrier. Is it worth getting or not? |

Like the bottom pic I posted or the top one in Rooster2's post only with a longer ledge at the back like an M16 carrier.
Just buy the RRA if you need a carrier. |

Please tell me you're joking. I don't know if the differences are good or bad, but there obviously are differences. On the RRA you can see less of the firing pin because it's covered by more metal, and the back end of the carrier obiously is "longer", for lack of a better term. Again, I don't know if this makes it better or not, but it is certainly different. |

 RRA standard carrier, RRA enhanced, Colt M16 One thing that is neat on the RRA enhanced is that they now chrome inside the gas keys too. |

isn't one of the advantages of the RRA "enhanced" carrier over the older style it's greater mass (e.g., more metal), thus helping to slow cycling?

Can you see the firing pin at all in the bottom pic I posted? ETA, I see your guys' problem. What you are missing is that the bottom pic I posted is NOT AN RRA CARRIER! It's a fucking M16 carrier with the trip face milled back. I'm comparing a "normal" carrier (as I used the term in my post) to the RRA, not a slotted carrier to the RRA. Years ago that's what semi carriers looked like. Then Colt modified the design and a lot of the makers followed suit for a variety of reasons. |

I have been using the RRA Carrier for a while. I like it. The chrome lining saves me a lot of time cleaning.
I just ordered another for my other AR. it is worth the money. |

The M16 carrier is better than the RRA "enhanced" carrier. The only thing enhanced about The RRA is it is less butchered than other carriers from the M16 spec. I say run with what was meant to be there... an M16 carrier. If you dont want to go to the hassle of findingn M16 carrier the RRA is the next best thing.

That is also a standard feature. Have I mentioned I really hate marketing weasels? Nice to see that my arguement about the M16 carrier being closer to the design weight of the rifle is now a selling point of a lightened carrier.

 Tweak, are you referring to my post? If so, I was inferring that the "new" RRA carrier's improvement over the "old" RRA carrier is that is closer in design (and weight) to the original. Perhaps you were referring to something else, but if not, what's wrong with my statement? (I apologize in advance if I'm incorrect here). |

You "imply" I "infer".  Nothing wrong with your post WS, you weren't the first to make the claim and that is why I stated that I hate to see marketing weasels using it as an arguement for lighter carriers. |

 Got it. I guess we're on the same page since the reason I run a "9mm (tungsten) buffer" in my M4-gry instead of an "H-type" is to compensate for the lesser weight of my "enhanced" RRA carrier vs. the "correct" weight M-16 carrier that the system was designed around... Roughly speaking, my rationale was [RRA carrier + 9mm buffer] approx = [M16 carrier + H-buffer] in the mass/weight dept. I'd like to get my hands on a "real" M-16 carrier sometime...haven't seen one in far too long (yep...I'm missing the 'Corps). |

So wait, you think that it is better than their standard carrier, but you're upset that they called it "enhanced"?
 I wouldn't care if Jessica Simpson changed her name to Fred Jones, I'd still hit the hell out of it. Something about a rose by any other name would still smell as sweet. |

If I went out and bought this new carrier group, would I have to get the head space checked? I assume not because I am only replaceing the bolt carrier and not the bolt.
For some reason I like the idea of more metal on the carrier. Anything closer to what the origial design is has to be a good thing. Plus the added chrome would make for easier cleaning. |

Tweak,
Is this what you are running, or something you modded yourself? http://www.sawlesales.com/jsps/sku.jsp?field=Part&value=SP63162 Does RRA properly stake their shit? |

If you change the carrier you do not need to recheck the HS. On a good day the HS exists only between the barrel and the bolt.
JLM, Do you mean the modified M16 carriers? I buy them in OR and mill them up here. The RRAs I've seen have been staked. |

After reading about this, I thought I might get one of the RRA "Enhanced" bolt carriers for my new Bushmaster. However, after looking at the carrier out of curiosity I noticed it looked like this...

I like the RRA carrier. I use it in combination with a Colt bolt, and that gives me a close-to-M16-spec weight, PLUS the hammer nose doesn't get torn up, PLUS the firing pin retaining pin doesn't get beat on by the hammer dragging on the pin. There are lots of good reasons to use either one of these or an M16 carrier.

Why? I am at work, and I will check when I get home. :) If my carrier key is not chromed, then I'll buy a new carrier key and forgo the whole new RRA carrier. If it is chromed, then sweet... I don't have to worry about it. |

My understanding is the RRA is like the M16 carrier, with the shrouded firing pin, but has the short sear engagement surface of an AR15 only carrier.

It's right between an AR and M16 carrier.

Only real bottom feeders use unchromed keys, they're cheaper but the time spent looking for them offsets the cost. If you happen to get an unchromed key in a kit you'd do well to be suspicious of the rest of the parts. Chromed is standard and is not an "enhancement" marketing weasel verbiage to the contrary. |

Well, again.. I have a bushmaster gun. I diden't think that bushmaster put a carrier like the RRA "Enhanced" in the gun by defult, but it looks like thats the case. |

BFI, like all the rest of them, will put whatever parts they have on hand into their rifles. It's economics. Your's may even be an RRA carrier if BFI had got them for a good price. But, there is still nothing "enhanced" about them, they are stock carriers.
