Very nicely done. Doing a retro AR the right way can take a while. 6 months to 2 years is a good average, depending on the difficulty of the build. 601s are getting more difficult to get parts for unless you are prepared to fork over some serious cash for the parts. I spent nearly 3 years on my XM607 before I could take it out and shoot it. A little over 2 years acquiring all of the parts and having the stock installed on the lower and another 8 1/2 months waiting on my tax stamp. My XM177E2 took almost two years. Most of the others took about 8 months to a year. I love the retro ARs. That is why I have a few of them.
