| Just got done with my first build and as mentioned in the subject, Mega Lower + Noveske Upper. These were recommended to me as top of the line components for my build, however the fit between the 2 is not top of the line. I know I'm being picky/ OCD but that's me. I'd like some advice on this. I plan on using maybe an o-ring or accuwedge as a temporary fix. But my strategy for a long term fix for the slop is to just buy a matching Noveske lower and scrap the Mega. Just wondering if the lower from Noveske might have the same problem. I used to own a RRA that had ZERO slop and perfect fit. That gun was less than a thousand, this gun between the Noveske Upper, Geissle trigger, Fail Zero bolt carrier, cost way way more. I'm just not happy with it, and won't be unless I fix this. I wish now I had just bought a complete rifle and added in the performance parts. Comments/ advice appreciated. |

A ar15 is always going to have some slop between the two. Just the nature or the beast.
I do believe that RRA always had a tight fit. My DD was nice and tight at first, but has since gotten a little play between the two. My own built gun has done the same thing. If it bothers you that much I would just throw a Oring on it and be done. Accuwedge=poop |

If you want a zero slop fit, other than by blind luck of the draw, you'll need to order a matched upper/lower combo, and build up from there, or send the parts you've got out to a custom gunsmith to be machined and mated together for the cosmetic fit you desire.
The quality parts you've got will fit and work together in a symphony of perfect harmony, but that doesn't mean they'll fit together airtight, since that's not part of the design criteria for an AR-15 type rifle. |
| I have a Noveske uppaer and lower, purchased seperately that are a PERFECT fit! Rifle has a couple thousand rounds through it, and I haven't been nice to some scoot and shoot stuff, still tight as a frog's butthole. I have tried my Noveske upper on other lowers (Bushy, Colt, FN, DPMS) and it has been super tight on and off of all those lowers. I had to drive the pins out with a leatherman........My opinion is scrap the Mega lower and get a Noveske |

I just recently received my matched Noveske N$ upper/lower combo..the fit is perfect, but like I said its a matched set..as mentioned before the AR is naturally going to have some play but I gaurantee it will function as designed. Every AR/M16 Ive ever been issued or used had play, except for my new Noveske set

You aint seen loose til you seen my Bushmaster. That thing is as loose as a retired hooker. How loose is loose? All my AR's are a little loose. Even my RRA that was so tight I had to drive the takedown pins with a punch is loose now that its got a couple thousand rounds through it. I think your being a little picky but if your not happy buy a new lower. I will buy the MEGA lower from ya

Once again, Mega lowers have a tension screw that you can use to tighten the fit between the receivers. You don't need to use an accuwedge or o-ring to do it. Only the billet sets have this. Are we sure he's got the billet set? Maybe I missed it somewhere. |

| I should have mentioned I have forged Mega lower, sorry. Don't have access to a mic at the moment. The issue is only in the rear lug and pin. There is a side to side movement that while slight, annoys the hell out of me now and can only imagine what it will be like trying to aim. Maybe a noveske lower is the best way to go, though I don't really know where to source one since rainier arms has them on back order. Sorely tempted to order an entire rifle from Noveske and in the trigger and 9310 bolt and failzero bolt carrier. What the hell I'll do with the build I have now, I'll just figure something out. Oh yeah, that mega is a forged lower, and it might be for sale......... |

If you don't like the fit then perhaps the AR15 platform is not for you. You fail to provide any useful feedback. Rather, I see what you're saying but your delivery needs a little work. I built myself a MEGA upper & lower build and there is some play. As others have mentioned, that's normal. Unless you have some ungodly gap that will clearly allow debris to enter the receiver assembly, it's not going to hurt anything. I owned a RRA lower and the fit was super-tight which I liked. The fit on my LMT Defender isn't as tight as the RRA was but the LMT is a hell of a shooter and I've never had any problems with it. I think what the poster I quoted was trying to say was that if you're stressing over receiver fit then get ready because there are a lot of little things about the AR platform that can prove to be challenging with respect to parts & performance. Receiver fit is way down at the bottom of the list. |

just throwing this out there for others that are watching and may not want a billet lower matched upper set.
tactical innovations forged lower has an upper receiver tensioning screw built in and rear detent capture screw. worked great with my bcm upper. lower is $ 100. once again not trying to take any thing away from mega, they are sick! just showing a different option for different folks. |

Nice. Wish MEGA did this. Don't want the billet due to weight. |

AggressivePerfector, I am planning a Mega build now. That is why I am reading this thread. If you need a Noveske lower try the people at the link below. I got four of these about a year and a half ago. I have used two of them and they are fine with Larue and Vltor uppers. Mine must have shipped as soon as they hung up the phone because I had the in three days.
