Most (if not all) of the original Colts use a .312 take down and pivot pin. All of the aftermarket ARs use .250 pins. There are adapters available to allow you to mate the two.

The story I heard on the geared down AR pictured previously was that someone at Surefire did that just to try and put "one of everything" that they sell on the rifle. Looks like it's true anyway, LOL.
