| I bought a Rock River lower last month and put it in my safe. When I got it, it looked a little dry and chalky. I put some Rem oil on it and it appeared to help it. I pulled it back out about a week ago and it's chalky again. As bad if not worse than when I got it. What gives? Is this normal? Is there something else I need to put on it? Matt |
| Tell me more. I ain't in love with them. The only reason I bought one is because my ffl holder has an account with them. A bunch of us guys at work got together and all decided to get one. I have a Colt, Bushmaster, and a Ameetec Arms AR already. None of them has chalked up like this one. Matt |

Seems just lately that Rock River and a few others out there have been unloading poor quality parts onto the market. May I suggest you check the fit of the lower to one of your uppers as there have been many negative reports about the fit but all the sycophants out there who think RRA are the best thing since sliced bread wont admit it.
http://www.ar15.com/forums/topic.html?b=3&f=66&t=282974 As to your finish for the price you paid for that lower you should not be expected to keep clp ing it just to get it to an acceptable condition. If it was me I would take it back to the dealer and ask for my money back or to exchange it. As a former British Ministry of Defense mechanical engineer I would say that the problem lies with the anodizing procedure and that it will only get worse. Anodizing is a form of controlled corrosion and the white residue is corrosion so clp ing it will help but it is still corroding. |

Or maybe the OP's question got answered and people saw that there wasn't a need to add anything to it. I'd give the same advice on any lower that looked gray and dull.
Yea but if it had been anybody but a Rock River lower then about a million people would have been posting all sorts of advice. But you cannot say what needs to be said on this forum about ROCK RIVER CRAP OOPS! DID I REALLY SAY THAT. I thought Tuesdays were the day for "bash the brand of your choice" posts... EVERYBODY has had some visible goofs hit the market in the past year-it's due to far more demand than anyone can keep up with. |

But you cannot say what needs to be said on this forum about ROCK RIVER CRAP OOPS! DID I REALLY SAY THAT. Most of the big names are produced by the same three groups from what I understand. Stag lowers come out of the same factory as RRA. So, bashing one single company without any mention of the other companies with the exact same specs is silly. |

That's just Rock River's piece of shit finish they use. If the world ever runs out of sandpaper, there will always be RRA lowers to fill in for it.
If you haven't yet, try fitting an upper to the lower. You're probably going to find that at the rear takedown pin location, it's really tight. You'll have difficulty closing the upper onto the lower. |

You'll have difficulty closing the upper onto the lower. I've never seen a RRA receiver with a "sandpaper-like" finish. The surface of hardcoat anodized material can really soak up some lube, but that's not really a problem. I've seen other makers' parts look exactly the same after being degreased. RRA intentionally makes the fit of the takedown lug and the lower's lug space very tight. It makes the receivers fit VERY tight. This eases up after a few hundred rounds and a few "break down and clean" cycles. No biggie. I'm no "fan boy" or anything, but having compared Stag, RRA, and other brands' uppers and lowers side by side, I haven't seen any real differences, let alone any reason to say "Brand X is shit because..." It's not like any of these real brands are Vulcan or anything. |

My RRA has a real nice look to it...so i just ordered a RRA stripped lower to build me a 20 inch flat top for a scoped long range shooter.Hope the lower looks OK.
When i was shopping locally for a AR i looked at Bushmaster,CMMG, DPMS,and it was the look and reputation that sold me on the AAR.
