I've been seeing a lot of these around lately - used ones taken off M-16A1s at gun shows and the ones CDNN had (they're now out). Since I've also been thinking about putting an AR together (not a full build, just buying an upper and lower, etc.), and, since everyone I shoot with has the M4-style AR's, I thought a retro M16A1-style gun might be fun for something a little different.
All of that said, will one of the Colt SP1/M16A1 uppers present any problems for me? Will I have to use a Colt lower, or can I use another type (say, a Double Star, for instance)? I've been doing some research here (using "search") and it seems like this should be no problems, but I'm not sure if I'm putting what I've been reading together the right way.
Thanks.
