[QUOTE="DasSieben, post: 2666000, member: 29823"] Coltdogg: How did you get an exact measurement on your gas port? I was switching out the gas blocks and tubes tonight and the gas port on the non-functioning upper is visually smaller. A 5/64" drill bit fits tight in non-functioning upper and same drill bit has play side to side in functioning upper. The ports look like they had a good seal from block...perfect circle on both ports and didnt look like there was any blow by on either one. So im leaning toward reaming out the smaller port. Do you or anyone else have any thoughts? [/QUOTE]
