I was thinking about getting a RRA Enhanced Bolt Carrier group. Have there been any problems with this group concerning its function and reliability? What exactly is enhanced about it.

I know their regular bolt carriers are are dependable. What about these

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

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?
Link Posted: 10/1/2004 3:43:43 PM EST
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?
Link Posted: 10/1/2004 6:58:37 PM EST
i like mine...havent used it yet...still building the rifle..but i think it will be fine...if not i lost $99bux

I don't see any difference between those two pics.

Tweak, what do YOU run personally?

Please point out the differences.



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.
Link Posted: 10/2/2004 5:50:56 AM EST
I've fired about 2K rounds with one. No problems...
Link Posted: 10/2/2004 6:35:47 AM EST
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?

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.
Link Posted: 10/3/2004 3:57:21 PM EST
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.

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).

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).

Link Posted: 10/4/2004 5:18:36 AM EST
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?

Does RRA properly stake their shit?

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...

Funny, I guess I don't need one. For ref. I have the XM15 E2S 16" bbl.

That sounded like a sarcastic joke...
Link Posted: 10/7/2004 5:20:06 AM EST
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.

It looks like it is. Or its just bright stainless.

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.

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.
