Medic650, My barrel was 7 inches to start with and I move the gas port in 1 1/2 inches to get it to run with or without a can. From what others have said the 8 - 81/2 inch barrels do not run well without a can with the standard pistol position gas port but I have no personal experience with that length. I do not know what loads they were running but my setup will run subsonic with bullets as light as 110 grain. I've not tried any super loads yet as I am still working things out with it but it does show promise.
