Quote HistoryThat image does a good job of illustrating the contours, but it's not exactly what I was hoping for. I was hoping to have something that would show what the dimensions are as the contour changes. For example, it would show what the distance is from where the chamber contour ends to where the contour for the gas block starts and also tells you the diameter of the barrel in that section and so on. I guess I'm looking for the specs to "blue print" a barrel with if we were to talk in machine shop terms. Thanks Wes |

That aside, I'm actually looking for the specs because I'm considering turning down a barrel I already have on the way that's 18" with a rifle gas system. I'd like to know just how much further I can cut it down based on the military testing done when the A1 and A2 were accepted for production. Thanks Wes |

I believe the slimmest part of the A1 profile barrel is .570 which is forward of the FSB(.625) and under the handgaurds but I've never measured it and am not home to measure one. Someone that knows the exact measurements will be along soon enough.
ETA: NDS sells Retro Receivers, not Barrels.... Do you want to buy New Replacement or Original? |
