So I took the gas block and tube back off last night, and based on the carbon pattern, it looks like the block was lined up dead center on the port. The gas key is definitely tight and the rings are not causing any sort of leak, so I think it must have been the dirt and grime. I did run the BCG pretty wet to start off, but may need to do a little more to the buffer and spring. I weighed the buffers I have and they are both standard Carbine weight, so I'm thinking with the Chrome Silocone spring and a better lube job, maybe some Froglube, I will go back out and see how it cycles tonight. May be able to wrangle up a heavier buffer to help if it is overgassed as well. Thanks again for all the help everyone!
