A CNC machine, no. A mill would sure make your life a whole heck of alot easier, but it can be done, if you're careful, with a drill press and hand tools. There's an article floating around on the internet of the Mujahideen AR15 build, which I think was done even without a drill press. It's just a question of how much time you want to invest into the project.

If you do not have the time or the required tools it might be better to just buy a stripped lower and parts.

Start Here Tons of good info. You can get the mag well wire edm'd for $35. The rest is pretty easy if you use "The Fixture". Follow the threads before you start until you understand the undertaking. Other info at: More info Some more drawings: Another source for prints and advice Note: The DSA part is a raw forging generally conforming to Army P/N F8448641––- Anybody out there have the forging drawing (not the drawing of finished p/n 8448608?? Personally I preferred doing a billet lower... But that requires machine tools that most people don't have... WB |

The Ray-vin (Ray Brandes) tutorial is the last word on machining a forging. I highly suggest you read this ~80 pages before jumping in.

if you're going to do an 80% lower, you might as well just buy a stripped lower from Essential for $105. The only reason to build a raw lower in my opinion is because you enjoy tinkering with machining. I have machined 8 raw lowers, but then again, I am a hobby machinist and have access to a full shop. +1 for Ray Brandes....his guide is THE place to start with regards to 0% lowers.

Hello.
I'm out of 60% or 80% lowers as of yesterday. I do expect to finish EDM'ing the mag well and having product for sale right about Tax Day. Yeah, no kidding. I'm also rolling out a Dedicated 9mm lower but have not finalized the style yet... Colt/RRA or Olympic Arms. Again, available just after the 15th. These will be 80% "max completion" lowers. Our 60%'s got great reviews. Here's a link to our site: YellowLogic lower I will repost with new pictures and more info in 2/3 weeks. |

Those lowers look very nice from yellow but seem a little pricey when you can get a ready to build for well under $200. Still, for something off the radar it may not be so bad.
