Any of you guys with milling expertise tried this? Or know of anyone capable? This is a thought for a C7 upper.

Coincidence! I have just bought a flat-top upper in the white for that very purpose for my next project. I am going to take off the bump myself and have the upper/carryhandle/lower set anodized Colt gray (its a removable A-1 carry handle).

Someone pointed out to me that 9mm uppers can be had w/o the bump, then a gas port and cam pin recess added much easier. Just a thought.

Thinking about an early M16A1E1 prototype clone, before the bump was added |

About a year ago Boywonder77 and John Thomas were posting some pics of the M16A1E1 collection at Rock Island Arsenal that I saved to my desktop. The non bump A2 upper with rear sight window is about the only A2 upper I personally find interesting.
Oh and the camo pattern on one was amazing too. The thread was titled M16A1E1 Build Guidance if anyone is interested in seeing the pics of what I have in mind. |

I used a RRA 9mm upper for my superlight build, I ended up with a 14.5" BM Superlight barrel, 2 position fiberlite stock, standardBM E2S lower with standard LPK, Semi auto, BCG, CH, CAR HG's, etc. Build came in a 4 lbs 14.65ozs.Weighted just about 5 lbs with an empty 30 round mag, and 5 lbs with a 20 round Pmag with 10 rounds. |

Neat to see how the engineers at Colt tested new ideas like that. |
