Am I the only person who likes Rock River Arms?

RRA BCG. I am not saying that another one wouldnt last for thousands of rounds, but the one we had did indeed break. I also swapped out the commercial receiver for a mil-spec one. I did that because my other two AR's have them, and I wanted to be able to swap stocks if I wanted. While I was doing that, I went ahead and put in an "H" buffer.

Are you able to be positive it was a Rock River bolt that was bought at the gun show and which broke?

I ask because after several years on the gun boards I do believe your experience would be the the first time I have heard first hand report of a RRA bolt breaking.

I can't remember ever hearing of RRA gas screws loosening either, even if not staked at all.
 
^^ What makes a bad AR fall apart is running it hard. If you shoot a few rounds a week at a range, where you can't shoot as fast as you want, or if you don't run it in a classs for example, basically if you don't throw a ****load of rounds downrange quickly, your AR will serve you well.
However, a bolt that isn't MP inspected, not HP inspected, a carrier key that isn't staked properly, are much more likely to brake than a Colt or an LMT for example, well in fact a carrier key that isn't staked WILL fall apart, it's one of these steps that is mandatory in building a good AR.

I wouldn't say that it WILL fall apart...there are plenty of cases where RRAs, BMs, DPMS, etc. have run just when when used hard. What matters is that there is a higher PROBABILITY of a problem due to not following the above QC procedures. For example, I have read that MPI and HP-testing a BCG reduces failure probability from 1 in 500-1000 to about 1 in 500,000. How much those odds matter to you depends on your situation and your comfort with risk.
 
There is not a Mall in America is defended with a DPMS, RR, BM, or OLY... I can tell ya that friendo...

:p

What makes these particular bolts so susceptible to failure? I don't read anything about persistent bolt failures in any military type rifles, including AR's. Why is that? (Except on this board)
The 5.56 is small and not a particularly high power cartridge, so why the high (supposedly) failure rate. You AR guys tout these things as the epitome of high tech evolution, supposedly passed the AK years ago as the best. I don't hear of bolt failures with 50 year old Combloc AK's and SKS's, and the only testing those bolts likely had was to see if they fired a round and cycled the action.
So, what is the deal. Is it inferior materials? Not likely with the metallurgy we have these days. Is it inferior design?
 
Who knows rockit... sounds like no one really "knows" but they all have a really good idea?

I would love to see how my AK's did in one of these Carbine Courses... as long as there is not a while lot of shooting over 200 yards I bet they would do pretty well....

Nothing. MPI and other testing methods do not make the product any better, they just help insure that a defective product doesn't leave the factory. Magnetic Particle Inspection, for instance, checks for surface or near surface flaws.
 
Really nothing wrong with a RRA as long as it suits you and you have a BCM bolt carrier group in it or as back up before classes.

But they don't offer any models, to the best of my knowledge, that suit me. For a basic rifle I'd rather have a Stag. And their fancier models allways have the wrong barrel twist, FF tube, gas block etc. Unknown which ones have M4 ramps?

And more often than not they really aren't much cheaper than a BCM build.
 
I guess all that really matters is that YOU like YOUR rifle. And that YOU are happy with YOUR rifle. And that YOU trust YOUR rifle and chosen rifle manufacturer.
 
Well, I like my RRA LAR-8 just fine, except for cleaning it all the time. I am not worried about a broken bolt or any other parts so I will buy more ammo with my spare parts money.
I think it and my Commie weapons kinda compliment each other.

Just as soon as I see some pics of an exploded bolt...or even hear a documented story about one exploding...(outside of mudslinging and hearsay) I'll get right on this worry train.

The most likely reason IMHO is due to the AR's direct gas impingement action. The bolt is cycled using the hot, high-pressure gases from the exploding powder of the cartridge, rather than using a piston rod driven by these gases a la AK-47. DGI has its advantages, but a downside is greater wear and tear to the chamber and bolt carrier group from said hot, high-pressure gases. This effect is amplified in a carbine-length gas system due to the more rapid cycling.

Seriously, people should be getting this tattooed on themselves.
 
I'd like them a lot more if they still made .45 lowers that took grease gun mags. :)


Also, is a Canadian berating us for daring to use an inferior rifle? Are you really claiming that you A. fire over 20k rounds a year and B. regular take your civilian AR into combat? I lol'ed, oh the mall ninja-ness. Reminds me of all the people who scoff at carrying a handgun that won't put down a raging grizzly while they live in CT...

So, because I am a canadian, I don't know crap about firearms? I'm the one who's "lol'ing" right now. I'm pretty damn sure you don't know anything about guns in Canada for that matter.

And canadian grizzlys are some pretty big beasts, unless you live in Canada, you don't know what I'm talking about neither.

Something tells me there is something personnal under all these thoughts, you don't like the olympics being in Vancouver CANADA don't you? We're all soo soo sorry.

No, but your attitude in this thread and willingness to sling mud w/o fact to back it up...combined with being Canadian...has robbed you of 90% of your credibility here.

Thanks for playing.
 
:rolleyes:

I don't like mall ninjas. The number of civilians who go into active combat zones with AR's is vanishingly small compared to the overall market share of ARs sold. The number of Canadians who do that sort of contract security is even smaller.

Now, maybe you really do fire 20k+ rounds a year and take your civvie AR into combat. But I really, really doubt it. And that makes your snide little remarks at the start of this thread even more pathetic.

As for "America's hat" I don't want to live there, but as long as you keep your oppressive laws (jailing pastors for "hate speech" gun registration etc) up there where they belong I don't really care.
