This cant be right...
My buddy just picked up his RRA 1251"Entry Tactical" from our FFL the other day. He had a bunch of accesories he wanted me to install on it as soon as he picked it up. So he dropped it off to me. When I took it apart to install the LaRue handguards I saw this: This carbine was purchased from a highly recommended dealer from the EE (name withheld until I clear this up) as a "new in box" 1251"Entry Tactical". What is up with these feedramps??? Are all RRA ramps dremel'ed like this? Anyone else's RRA have these style feedramps? ***Incase its not clear from the pic, the ramps look like they were cut into the reciever by a dremel tool, and the anodizing is gone on the reciever cuts*** *ETA: I was goin to refinish his barrel with Norrels because when I removed the FSB to install a PRI flip-up, I scratched up his barrel a bit. When disassembling the upper, I could not get the barrel to seperate from the reciever after removing the barrel nut. On all of the other uppers I have worked on the barrels come off easily after removing the barrel nut. |

E-mail the pic to Steve at ADCO. He knows more about RRA's than most folks, and will give you the straight scoop.

I dont think there will be any function problems, but it doesnt look like what I expected from a factory RRA rifle. |

I just received a DPMS M4-style upper and the feed ramps looked the same way. I called DPMS and a tech said that was how they were doing it so they could tell which upppers they had assembled in-house vs. those that were assembled by "unscrupulous" dealers and sold as factory DPMS uppers. I asked how they would be able to tell the difference between one of their "dremel" jobs and a "dremel" job by an "unscrupulous" dealer and they didn't know. I was thoroughly confused by their flawed reasoning.

I bought a RR Entry Tactical about a month ago.
The M4 feedramp cuts in my upper are smooth, but not uniform when comparing one to the other. It looks like the cuts in the upper reciever were made after the barrel was installed, using a dremel. They are not very well done. I have an Armalite AR-10 carbine with M4 feedramps cut in it. The cuts in the receiver were made before the upper was finished. The cuts in the upper receiver were deeper than the cuts in the barrel extension, leaving a ledge that the bullet tip would likely snag on. I dremeled the cuts in the extension till they matched the cuts in the upper. My guess is some manufacturers are putting M4 barrel extensions into uppers without the cuts and then installing the cuts in the receiver to blend into the cuts in the barrel extension. Just a guess. |

Thanks for the responses guys. I was just surprised when I saw them after hearing about RRA's "top quality" products, and comparing them to my carbines (MRP) feedramps. I always thought the anodizing was there for a reason

If you want factory anodized M4 feedramps your options are CMT, LMT, AND Colt. For the money AND quality I recommend the CMT uppers. I don't understand why anyone would choose a Dremeled upper over CMT, but if it makes you happy...

Thats a shame if that was done by RRA. If so I wonder how much they paid the guy with the drimel? If thay want M4 feed ramps. They should tool up for it.
If this is RRA's R4 style ramps way of differing from M4. To avoid legal matters with Colt. I dont think Colt has a leg to stand on. As these are nothing like Colts M4 ramps. I'll stick with Colt's edit to add. Oh ya or LMT. |

Believe there is a thread somewhere else on this topic that Steve@Adco did answer and this is a new "improvement" RRAs is doing. Those cuts are on my Varmit upper.

My CMMG upper has dremeled feed ramps, but they look nothing like those.
They actually look like M4 feed ramps are supposed to. That just looks...pathetic.

Does anyone else out there have an RRA Entry Tactical that they could check the feed ramps on. I would like to find out whether this modification is on all the guns they are building, or is it an oddity. Please check your rifles and give us a heads up.

My M4gery from M&A Parts
 My Rock River 20" I bought off the head armorer at Rock River  Looks like my M4gery has a rifle barrel extension and an M4-type upper. My Rock River has the same marks you show so I wouldn't worry about it too much. Edit: Hope these aren't too big |

That just ain't right...
RRA is going to get a recommendation demotion if this is how they do M4 ramps now days... Even the M&A pics of M4 ramps looked "unmatched." Good, bad or whatever, my Colt M4 ramps are anodized and match the barrel... That's how it should be done by ALL M4 manufacturers... Rmpl |

I did one better. I just ordered a CMT M4 upper from you to replace this butcher shop job. Doesnt CMT manufacture RRA's stuff anyway? Why wouldnt they just use a CMT M4 upper reciever instead of butchering a A3 like this one??? |

Are you sure that barrel has an M4 barrel extension? It doesn't really look like it in the picture compared to the pictures and informaiton in the adco post. |

I've gotten factory RRA uppers like that (well sort of like that other than the slip and unequal ramp on the right). Not true M4 ramps and it looks like that is a rifle extension not M4. You might let Grant know to send a non M4 ramped upper

CMT does do RRA's lowers because they have a "CM" prefix on the serial number just like the CMT lowers. |

All Armalite receivers have the M4 type extensions in them from the factory, including their .308 models.
It just looks half assed, therefore, I agree. |

Looks like a RRA upper to me. They have always tapped the upper with a Dremmel. I'd just shoot it and not worry about it. It will function just fine. Its a rifle, a tool. If it goes bang thats all that matters, right

RRA may have done it, but I disagree with the "all that matters" stuff. I just got a DPMS factory upper with Dremeled ramps and I'm pissed. The problem is that there is no standard for Dremeled ramps. These guys are creating custom barrel to rec ramp cuts that will not match anything other than the mating part that it was cut with. I was going to swap this barrel to another rec and this rec to another barrel, but now I can't unless I want to Dremel yet another barrel and rec. |

I'll just use it for my 6.8 project. It just puts me one step closer. Thanks Jason It just doesnt make sense...It seems they (RRA) will loose more $money$ from potential buyers being turned off by the quality of workmanship (lack of) with this type of short cut. If CMT does indeed manufacture RRA receivers, they make M4 receivers, so why not use a CMT M4 upper with a real M4 extension??? Of all the dealers selling the CMT stripped uppers, I havent seen a difference in price between the standard and the M4 uppers. What is the price diff. between a rifle or M4 extesion??? Since they raised their prices this year, its the least they can do. Along with letting my buddy trade up to a real M4 upper
