I'm thinking of trying my hands at building a lower using a polymer from James Madison tactical and a 80% easy jig. I'm hoping that as a first project this setup won't be to hard to mill. If I can get a nice finishing I'll  probably try an aluminum version. But before I invest in this setup, can anyone else point me to other jigs that may be even easier? I've Google around but there may be folks that sell other jigs that I may have missed. Any suggestions? Thanks

The JMT lower comes with a jig.  

The 80% easy jig is the easiest on the market, hands down.

You can get an aluminum lower and mill it out with the easy jig no problem.

I just finished a lower with the Modulas Arms jig and it was easy.

The finished pocket was smooth and I did not have to touch up the sides at all with a file.

Can anyone recommend  a good 6061 aluminum 80 lower with the rear pocket complete? All these choices is giving me a headache? Thanks

Tactical Machining has 7075 Gen 2 available now. On sale for only $29 if you buy 3. If you screw one up, you'll have back up. If the first one comes out nice, you'll come out ahead...

Milled rear pocket too.  These are 7075 like mentioned, not the 6061 you asked for, but with 7075 this cheap, there's no reason to cheap out here.  I don't know of any advantage to 6061.  It galls up a lot more and you almost have to use a lubricant.

I would also agree, the TM Gen 2 in 7075-T6 is the way to go...There is a reason why 6061-T6 is less expensive...Good luck.
