Looks nice. Do you have specs like weight, width/O.D. and I.D.?

Integrated qd points? The holes at the front and rear of the 3 and 9 o'clock slots look like QD points. |

Integrated qd points? Looks like it, plus they're anti rotation. I would have liked to see MLOK on the diagonals too, but that might be too close to the URX 4 |

Is the 6.7"rail actually 6.7", or is that anot approximation. Looking at this for my 9mm build....I like it and hope it will work.

I see you mention billet uppers, have you test specifically with a mega upper?

I'm really liking the looks of this rail. I think my Spikes upper might need one!

I like it for a LW build. Do you think CMT will offer a mod with full picatinny on top?

I bought one of these and I think they need some improvements:
- It doesn't fit standard upper receivers without filing the anti rotation tabs - The small amount of picatinny was out of spec (too wide) - It would be helpful to have a tiny relief cut at the bottom rear of the tube to allow fitment with a wider range of lower receivers |

Wonder if you got a bad one; mine doesn't have any of those issues. |

Well, I tried contacting them to find out and never could get a response. It would not fit four different upper receivers, and the picatinny most certainly measures too wide (which I checked after finding that a couple different accessories didn't fit). |
