What is this??
Any ideas? A take off from an old colt model of some type? 1-7 twist?

It looks like a standard M16A1 upper - R603. It has round handguards instead of triangular handguards.
Probably 1/12 twist barrel.
Pretty good deal.
Sold in two minutes 11 seconds. Appears Augee hit it right on to me.
