What do you mean when you say "machined for anti rotation by ADCO" about your upper receiver? Are you referring to QD slots on the rail?

No, the NSR's Anti Rotation feature consists of a tiny pin that fits in a hole just above the gas tube on the rail. ADCO now offers a service where they machine a tiny hole above the gas tube hole on the upper so you can utilize the anti rotation of the NSR. |

fucking sexy..........so let me ask, how does the NSR attach? does it utilize the standard barrel nut?

That's a fine build right there!

ADCO now offers a service where they machine a tiny hole above the gas tube hole on the upper so you can utilize the anti rotation of the NSR. So, does the NSR normally rotate? Why the specific modification to the upper? I guess I'm asking if the ADCO job is required for the full benefits that the rail provides. Also, did you have any problems with the CMMG LPK? Any of the roll pins oversized or other issues? Just curious because I have a kit waiting on a build. Thanks for the sweet pics! |

The specs for the NSR barrel nut call for it to be torqued to somewhere around 80 Ft. Lbs., and there are plenty of guys out there running the NSR without the anti-rotation pin that aren't having issues so I doubt it is a huge problem. I just felt I should get it done because this is a gun I plan to beat on and wanted the extra security. As for the CMMG LPK's I used two of them to build up two PSA lowers I had and neither of them had any issues with out of spec parts. |

Nice looking stick. Only thing I would say that looks out of place is the Matech. That rifle begs for a KAC micro.

Very nice.
I'm putting together a NSR build myself. |

Is that allowed to have a KAC front Taupe sight on a non sopmod build?

I've got a similar build, but went with the Noveske NSR Scout mount, it is a lot more low profile (and lighter). Just something to think about if you end up swapping out mounts down the road.

Them NSR's are really starting to grow on me. Might be time to start thinking about a new upper.

Yeah, eventually I'm gonna move over to a M300 Surefire and one of the NSR Scout Mounts whenever I can actually find one in stock.
