Just received the new CMT Billet Upper the UPUR-1. This this is sweet and was the perfect match for my Noveske lower. I had plans to do an all Noveske build but got tired of trying to find a Noveske MUR upper but I'm actually glad I went with the CMT as I like it even better.
CMT UPUR-1 upper Noveske FFL lower Spikes BCG Geissele SSA Magpul UBR This will be a RECCE so to finish out the build I will be fitting it with: 16" Ranier SS barrel Noveske NSR 15 Ranier Raptor AAC 51t 1-4x24 that is TBD

Uploaded with ImageShack.us *****My one issue. This lower on mates up with 1 of my uppers. The upper you see now you can notice the rear takedown pin is about 75% in and that is as far as I can get it in with my hand. I did tap it in earlier with a hammer and punch but I also had to punch it out and it was ridiculously tight! Anyone has any suggestions on the best way to loosen up the lug to make the pins a bit easier?

Always modify the cheapest part - I'd shave the pins to correct for the out-of-spec holes. (PS: Your pictures aren't working) Good advice. I'll start on the pins but this Noveske lower is a definitely a little out of spec which is not too thrilling on a 260$ lower. Thanks |

The fit of my noveske gen 2 is pretty tight with the mur receiver I have. I need a pen or other "tool" to take it down. Mine requires a metal punch and a BFH and a lot of force to get it the last 1/4 and to remove the pin. I've been working on it for the last hour driving the take down pin in and back out and it hasn't loosened up at all. Will try to work on the pins tomorrow. At least I will finally have an AR that doesn't rattle

Anyone has any suggestions on the best way to loosen up the lug to make the pins a bit easier? I wouldn't mess with it, I have guns that go together like that and if you ask me its better. I always carry a 10-8 performance tool or a Derlin Plastic punch so its no issue...I rather it be tight than start shaving or grinding to make it have more play, after time it will all work out. |

Knock it in and shoot it. It will loosen up over time. Until then use a Delrin punch as shooter posted to get it in/out.
I remember RRA lowers that were hella hard to get an upper onto. Put em together then shot the shit out of them and it would loosen them up a tad but still not easy enough to get in/out by hand for a while. |

I probably have 5 or 6 derlin punches and handful of the 10-8 tools, these are just good tools that are cheap and you can bring with you anywhere. |

I was not aware of the Delrin punch but I just placed an order for one. Thanks for the heads up on that. |
