This is the upper I purchased. Yes, I know it's entry level but so was my budget. https://www.ar15part.com/6-5-Grendel-Upp...fsg2rl.htm
It has a midlength gas system. The reason I believe it's over gassed is when you drop the mag out after shooting a round the top bullet in the stack is literally green and splotched like it had been in salt water for a week. When the .223 upper was on there it didn't do this. I also have a Radians charging handle that is supposed to help with blow back. Since I'm a lefty thats kinda helpful. Thanks for any info.
