Pin Size Colt 6933?

I can’t find this information on the internet.

Does anyone know if the Colt 6933 has standard .250 or .312 takedown and pivot pins?

I would like to replace the upper with one without the fixed front site.

I purchased two of them in 2006 and they had .250" pins. I’m sure that’s still true.

Thanks. I bought this one in Dec. 2008. I found this website and it suggested that the earlier Colts had the larger pins.

I bought two before you and they both have standard pivot and takedown pins.
