Guys, I just tested mine before doing the conversion. All I have to shoot right now is some cheap Remington birdshot. I ran it on gas setting two without issue. Then out of curiosity I checked the gas ports and found that it has only two. Considering that it cycled fine with birdshot, is there any reason to do anything about the gas ports? I might pull the gas block and check the diameter. Maybe it has two bigger ones?
