No worries, thanks for your time.
I would liked to have spend some more time talking about this stuff.
It would have been interesting to have machined on that stock some too. I'm going to get one of those mills I talked about and try it. I have some of the HSS end mills that I could stick in my drill press, but don't have the X-Y table for it.
On a side note, I forgot to ask you about the upper. I'm assuming it's a 5.56 model since it's an old Colt.
