Hello,
I am a new member to the site. Been here for a while, but just joined. I just purchased a RRA 5.56 complete lower from my local dealer. I am now looking to purchase a complete upper. I am wanting to get a RRA upper from their website. I know they are behind on shipping but they look good. My question is about the chambers. I have done a search and turned up a couple of explanations on the Wylde chamber but nothing that really answers my question. Basically I am understanding that the Wylde chamber will shoot both .223 and 5.56 rounds. My problem is that while RRA does indeed have the option of ordering the Wylde chamber, their "normal" chambers are listed as ".223/5.56". If they are selling them listed like that, doesn't that mean that they will shoot both as well? Finally; does it really matter. I am just looking for a gun to play with and use for HD. Tell my why I need the Wylde chamber or if the other is fine. One last thing; does anyone know the latest shipping story on RRA. Thanks for your help |

It is my understanding that the Wylde chamber will shoot both 223 and 5.56.
I also am waiting on a rifle from them and currently they are not shipping any weapons because they are out of barrels. The info I have recieved from them is they don't know when barrels are coming in and when they do what weapons will go out first. This is frustrating to me but RRA does make a good gun. In my opinion they are one of the better mid teir guns out their so it is up to you if you choose to wait. |

Thanks for your help From RRA: "The .223 Wylde chamber was designed as a match chambering for semi-automatic rifles. It will accomodate both .223 Rem and 5.56mm NATO ammunition. It is relieved in the case body to aid in extraction and features a shorter throat for improved accuracy." |

Thanks guys.
I had read the info from RRA's website and it helped but didn't explain why their "non Wylde" guns are listed as ".223/5.56". If the Wylde chamber is for both, why list the other chambers as .223/5.56. Just confusing. Ok, if I just get the non Wylde, normal chambered LAR15, what ammo do I buy, .223 or 5.56? Also: Can someone suggest an upper that shipping times aren't an issue with? I am open for anything good and fast. I can't wait a half a year on the rest of my gun. I looked at Noveske and they are amazing, but also amazingly expensive for just an upper. Thanks for the info. |

A rifle chambered for 5.56 will shoot both cartridges without a problem. However if you try and shoot 5.56 in a rifle (such as a hunting rifle chambered for .223, your asking for potential major safety issues. The guns from Rock River can all handle 5.56 ammo.
As far as ship times from different manufacturers, you'll have to call around. |

To save a good bit of $$$, once you decide on what you want, contact: 1. Legal Transfers, LLC 2. ADCO for pricing. Neither can advertise their actual price on the web due to RRA's pricing policy. FWIW; AFAIK; IMHO; YMMV; yadda, yadda, yadda. Regards, Ed Mann mailto:[email protected] [b]Bobby Bowden is doing a fine job and you critics should just leave him alone.[/b]

If the Wylde chamber is for both, why list the other chambers as .223/5.56. Just confusing. Rock river's standard chamber is 5.56. A 5.56 chamber has a longer freebore than a .223, thus it can safely shoot .223 as well as the higher pressure 5.56 it was designed for. .223 will not be as accurate from a 5.56 chamber (compared to firing it from a SAAMI spec .223 chamber) due to the increased freebore the projectile has to "jump" before it engages the rifling. The Wylde chamber has less freebore than a standard 5.56, but still more than the .223, thus it is considered a "hybrid" chamber. It is safe to shoot the 5.56 in this chamber due to it having the increased freebore as compared to a .223 (keeps chamber pressures down to a safe level with 5.56 ammo), while also giving slightly better accuracy (as compared to a 5.56 chamber) with both 5.56 and .223 due to the shorter freebore than a standard 5.56 chamber. Bottom line: It was developed to give slightly better accuracy than a standard 5.56 chamber while still being safe at 5.56 pressures. Unless you are a dedicated competition shooter you will never know the difference. Greg |

Thanks to all of you for your help, but an extra thanks to Greg (Spectre210). That helped out a ton. I admit I am a little hard headed but that topic was just baffling me.
Also Thanks edlmann for the tips on the links. I am in the process of checking them out now. So what it boils down to is with a .223/5.56 rifle, I can shoot whatever my heart desires as long as accuracy is not paramount. Thanks |

Thanks for your help You are going to have a very hard time to get one directly from their site in a timely manner. I ended up going here to get a RRA upper. They have a ton in stock. You can call and confirm they have it in and they ship fast. They have a ton of uppers and options to pick from. You will not be sorry.

As a side note, all of the vendors mentioned in this thread have excellent reputations, and with good reason. One of them should have something in stock to meet your requirements and all are very good about answering questions you may have about their products. Whatever you decide to purchase, have fun and be safe! Greg |

Thanks a bunch for all your help.
I am clear on what the chambers are all about now and, thanks to "zack991", I just completed my order with "pkfirearms" for a custom RRA upper. So far, so good. I didn't confirm stock, but hopefully they would have told me if they were out. 
Hopefully this will arrive next week sometime and I will post my results in here for anyone else looking for an RRA upper with the quickness and no time to wait. At first I felt a little guilty not going directly with RRA but in the end everyone gets paid anyway, so no problems. Now I am off to find the best place to get some ammo. I picked up my magazines over at MyGoTimeGear. They have a great deal on the Magpul mags. They are out right now but are backordering them. Thanks again. |

I haven't wanted to reply back to this until I had fired my new rifle and tested it out but I still haven't got around to that, so I figured I would go ahead and let you all know how the purchases went anyway. I can update the performance later.
As I already stated, I ordered the custom mid-length RRA upper from PKFirearms. This arrived in about 3 days, in perfect condition. It mated perfectly with the RRA lower that I had previously purchased from my local dealer. The PMAG's were ordered from MyGoTimeGear, and I knew when purchasing that they were on back order. I went ahead and took the chance. Within 2 weeks they showed up in perfect shape as well. All in all, I recommend these two vendors for anything. My experience was great. Hopefully all of the folks looking for RRA uppers that were dreading the wait time directly from RRA can see this post. PKFirearms is where it's at. Thanks again. I will post back with performance results. Possibly pics as well if I can figure that out. For those still hunting PMAG's, MyGoTimeGear will still backorder them if you can wait a few weeks. |

SixGunJr,
I was told this a lot as well. I even got into a semi argument with my local dealer and one of his countermunkies. But, according to quite a bit of research with the people that make them, not the people that sell them, this is ever so slightly incorrect. Tis true that for most modern AR's it is a non issue because they are built to handle whatever, but there are some gotchas on the "strength" of the two different loads that can show up on rare occasion, such as using a 5.56 in a .223 hunting rifle as Spectre210 and tbd1966 mentioned above. I may get overruled on this but that was my take on it. ETA: Credit to tbd1966 and Spectre210 for info. |

My understanding is that 5.56 NATO and .223 Remington rounds are NOT the same thing.
5.56 is loaded to higher pressures. I am by no means an expert but in what I've researched it is not the safest thing to fire 5.56 NATO in a true .223 chamber. However, a chamber marked ".223 / 5.56" should indicate the chamber is designed to accomodate the higher pressure 5.56 round safely as well as any .223. |
