Could anyone give me the skinny on these rifles other than the basics. I just bought one, and would love to hear the ins and outs from the most knowlegable Colt guys on the planet(that means you guys), and consolidate the information into one thread. Matter of fact, please share any and all knowlege that you might have on any of the "preban" Colt AR incarnations. I find the differences and anomonlies fascinating from the SP1 AR15's right up until the split off into the LE carbines and MT rifles after the 94 ban, especially the Sporter series. Original Colt ads would be great as well.
