You will get a very high quality upper that will fit very well with your Bushmaster lower. I have been very happy with the fit and finish of both RRA uppers that I own. The opinions I see on this board by others seem to reflect the same.

I've just done exactly the same to my Bushie lower (I call the result a "Rock Master"). The RR upper is of excellent quality. I expected this since I already had an RR lower on another gun. The color on RR pieces is very slightly different than on the Bushie, but it's not something you'd notice from more than 6to12 inches away. The only real lack in the RR uppers is the lack of the dry lube coating on the inside surface. I don't miss it, because the stuff rubs off, where the bolt carrier rubs, in two or three thousand rounds anyway.
Given the price difference between the RR and Bushie uppers, it's pretty hard to justify the difference and buy the Bushie. I'd recommend you save the money and build your own "Rock Master".

How cheap is the upper?? I am looking for one myself! J&T's M4 kit with A2 detachable carry handle is $550.

BlackDog checkout SableCo's website for super deals on RRA uppers. Donnie is terrific to deal with and fast on shipping . I wouldn't trade or sell the RRA CMP upper I bought,it is one tack driving shooter. HTH

I deal with one of the suppliers to Rock River.
The guy makes parts that fit ANY mil-spec part. The company is RB Precision. Check out the web site at rbprecision.com. You see why the stuff fits so well. I now buy most of my stuff from him. |

I agree with the comment that RRA are "Inexpensive" but NOT "cheap."
The main reason is that you are not paying for the name recognition that Colt and Bushmaster have. Colts are expensive because of their name "Colt" and they were who had the contract with the military when the M16 became popular and known. Bushy is the current military contractor, and people think that the military only buy the best (which is not necessarily so). RRA also does not spend as much money on Marketing/Advertising that Bushy and Colt do. As for quality, I'd put RRA against Colt and Bushy any day and it will hold its own or excel. You won't be disappointed. |

I beleive it was written inside their catalog in the company profile/background they state that they provided a batch of M4 in the 1990 time frame. I have to go pull out the old catalogs, yes, I do have some back issues. I rather have the pencil, need a spare writing utensil.
You might direct that question to the Subguns NFA board, as there is a fella(s) there that work or worked in the armory on a base somewhere that has seen Bushmaster M-16's. |

You must not be looking at their 1911's then. Rock River Arms made last year's LEGP, and many were impressed with the fit and finish of those guns. They have a good reputation for quality.Remember the Alamo, and God Bless Texas... |

Concerning Bushmaster's military contract:
Military contracts are a matter of public record. You should be able to find a contract number throught he freedom of information act. Also, I had a buddy who claims to have been issued a Bushmaster M-4 shortly after the Gulf War. I really can't vouch for it though. |

Here is my RRA/Colt Rifle:
Its the postban M4 Entry Tactical model upper with chrome lined bore/chamber, mated with a Colt MT6700C lower - other goodies include, Ergo grip, Fobus M33 handguards, low profile Ergo covers, RRA Tactical Entry stock and 1 3/4" Bushmaster extension for the buttstock:  Mattja - The postban "flash suppressor" is a standard A2 model, bored out and press fitted over the barrel, complete with locking washer for looks. As for the chome lined barrel/chamber - I think its a $35-$40 upgrade through Donnie at Sable Co. www.sableco.net I had a lengthy review on it in the Rifles/Uppers section here www.ar15.com/forums/topic.html?id=121038 |

I recently built an M4 upper with RRA parts from Pete-in-NH. They are some of the highest quality parts I've ever used at any price...and yes I've used plenty of Colt, Bushmaster, Oly, etc, etc, etc

The M4 Carbine has been around since 1986! And I believe the combo existed earlier, and was originally designed for an Abu Dahbi contract.
Bushmaster had a one-time contract to supply 3500 M4s to the US military in 1990 during the Desert Sheild build-up, because Colt couldn't supply them fast enough to meet the sudden increase in demand. Colt complained, because they held patents on the configuration, and ended up winning a single-source contract for the M4, which continues today. Still, the Army has already tried to award M4 contracts to FN anyway, but Colt fought that and won. Colt currently supplies the M4 and the M16A4. FN Manufacturing supplies the M16A2 and M16A3, along with the M240 GPMG, M249 SAW, and a number of other guns. For more on RRA vs. Bushmaster, read this thread: www.ar15.com/forums/topic.html?id=132313 -Troy |

Ok you and all thso reothers who are talking about Bushmaster in the 80's are going off track and are so full of it. I was responding to a claim the RRA MADE M4'S!!! OK? And I seriously doubt that they had M4's int he 80's and that they used them in the Gulf War since in 1993 the Delta guys in Somalia used CAR-15's (The stuff that the Isreali SF get standard issue albeit with A2 sights and grip and a few other mods, see: isayeret.com) (And remember Delta guys can have anything they want, so an M4 (if they would have existed back then) woudl have been no problem. Ask Mark Bowden, ask the Delta operator themselves, ask the DoD! Some of them are in Afghanistan as we speak (Mark Boden claims). You guys just romaticise the M4 too much. The M4's came about in 1994. Show me some proof of whatever Abu Dahbi contract. What the hell is that anyway? THEY HAD No M4's in DESERT STORM! BS BS BS BS BS!!! Perhaps a few CAR-15's. And to that old topic that you added: IN A WORLD OF COMPROMISE SOME DON'T!!! Buy the best gun you can because quality counts especailly if you plan to shoot regularly (meaning a few K rounds a year easy). Quality costs but rocks. SIG!!! SIG out, Doggonit (The SIGer strikes again) Knowledge is power... |

Doggonit,
Please refer to page 391 of"The Black Rifle" by R. Blake Stevens and Edward C. Ezell. There you will find two photographs and a description of the XM4 Carbine (Colt model number 727) as produced for Abu Dhabi. Since you'll probably call me a liar I'll include the ISBN number of the text, so that you can reference it in the future: ISBN 0-88935-115-5. |

IN A WORLD FULL OF B.S., SOME DON'T!
As for you all claiming that Ahboo Daabee is a country - WHAT B.S. Just ask the DOD. Just ask the operators, well, you can't, because they're stationed there right now. Knowledge is power, and the M4 didn't exist until 1194BC! Anyway I wasn;t talking about the M4 you idiots, I was talking about the m FOUR, which is a completely different weapon all together. Ask my close personal friend Marchinko. He'll tell you all about it, oh yeah, but he's in Afganeeeeestan. Whatever you get, make sure that it can handle 2,000,000,000,000,000,000,000,000,000 rounds a year. That's why I only shoot SIG AR's. (They had the original M-4 contract back in 2007) SIG AR's are used by the Israleee Special Yarmulka Command see www.stileproject.com Bushmaster made M-4's. BS BS BS BS BS BS BS BS BS BS BS BS BS BS BS The only M-4's that Bushmaster made were for the Iraqi National Home Guard Battalion. Just ask the INS or the AFT or the NICS or the WD-40! Quality costs, but when you're an operatuhr like me, you can afford it! Now do you idiots see what I'm saying. CRAP I GOTTA STOP SNORTIN SO MUCH METH! |

Please, please, stop the viciousness. I feel that you have effectively proved me wrong and even taught me a lesson. Sorry but spell check takes too long for me. I need to hurry. Despite devoting time to this board I can only do that in fast short spontaneous bursts so I might seem agitated. Well alright I admit I am. But that's just because of the pressure of hurrying to do this to do that. What a life...
So sorry folks for making you angry, I hope you wont attack me again. I guess McUzi was right... I guess I should listen more to my elders... But who would've thought that there was an XM-4? And how many where made? SIG out, The SIGer strikes again |

Yes but if you look really close most of the parts are from the same manufacturers. No doubt about Bushmasters quality but they are all very close. Even the J&T, Model "1" etc.
That's me a few years ago being hit with the stick. Sadly enough I still prefer Bushmaster even though I know better.

GIJohnny, saying place like JT and bushmaster get their parts from the same place is like saying Daewoo and Rolls Royce use the same metal to build their cars. True but very deceptive...
This stuff has been gone over and over here. There is so much info on this board you will never be able to see it all. But stick around and keep reading, you'll find some great info... IMHO, General Discussion forums are almost the worst place to go for good info. There is about as much bull crap info found here as good info. Doggonit, if you dont have enough time to spell check what you post, how much time did you have to think about what it was you just typed? Is it accurate or just "fast short spontaneous bursts" which have a tendency to be innaccurate? Not a slam or anything, just something to think about. |

I really like my RRA M4 post-ban upper. It looks and feels great, and that extra 1.5" has shown to have a good effect on effective range.
As to why they're so inexpensive: market penetration. RRA is relatively new and needs to make a name for itself. It can't charge the premium that ArmaLite, Bushmaster, and especially Colt charge. |
