Hey guys, i had my adjustable gas block turned down on my 6.8 so it would have the minimum amount of gas to cycle suppressed, and decided that i wanted it to be able to cycle unsuppressed as well. So today i began opening it up turn by turn and testing to see if it would cycle. It seems like the cases are getting stuck in the chamber, as it absolutely refuses to eject and i have to take a rubber mallet to the CH to get it to let loose of the spent brass. Now the adjuster is so open that im worried the hex screw will fall out! This is an ARP 5r barrel with a seekins gas block shooting xm68gd, AIM nitride bcg. I tried lubing up the barrel,chamber, bcg, swapping mags out, and charging handles to boot. All with the same results. However the minute i slap the can on it runs like a raped ape! Any input would be greatly appreciated, this is now the 2nd upper i have that simply seems to not wanna run without that can.
