Dane Armory Posted May 5, 2013 Report Share Posted May 5, 2013 Finally got to working on 300 aac barrels. Test fired one round today.brass looked clean with no scratches or lines. Green mountain 16 inch 1=8 twist blanks. Can I get gas port sizes for carbine gas system ? Quote Link to comment Share on other sites More sharing options...
98Z5V Posted May 9, 2013 Report Share Posted May 9, 2013 I can pull my upper apart next week, brother. 16" with carbine gas. I'll measure the gas port diameter. Quote Link to comment Share on other sites More sharing options...
