I was unable to come up with anything on a search so I am hoping somebody can give me some help with a question:

Does anybody know what the spec is on the gas port of a Colt 6920? I believe that the milspec gas port on the M4 is .062. But I am also wondering if this is the size Colt is specifying for their civilian 6920 or 6921 carbines.

Anybody have any experience with the 6920 gas ports?
