Here it is; from my experience they were a PITA. But you may have better luck.

Some Colt pre-ban lowers are small hole. I sold one of each recently. I ran the Colt large hole lower with a small hole upper using a conversion kit - it worked pretty good.

And there are other pre ban lowers - such as Eagle, that are small hole. (I have an Eagle, btw.)

First let me say that I would buy the Daniel Defense large pin uppers.

With that said "m60joe" converts large pin Colt's to small pin. He does this mainly on registered full auto receivers.
