Been doing some research today and the endless array of parts and vendors is mind numbing. Not sure if I should bother either. A Bushmaster might be the way to go.Nickle said:I'd go with a Bushmaster Lower and Upper (A2 Style, you can keep your flattop). Get the rest of your parts from wherever you want. I'd go with the 1-9" twist. Don't get wrapped around the axle about Colt parts. Definitely go w/ the Chrome Lined Barrel, never get a Stainless or Chromed Bolt. The military quit using them.
