My friend is getting his father's pre-ban Colt, which we're sure is just your standard 20" AR15. The rifle has only fired about a hundred rounds and was purchased new in the early 70's.

Anyone have any clue as to what twist it will have? He doesn't think it has a forward assist either, when did they add those to ARs? Any place on the net where I can get some information on these differences between SP1, Sporters, ect...
