Sounds like overgassed to me. A heavier buffer, buffer spring, and / or BCG might help. But based on my experience with midlength 18" 6.5's, the best remedy is an adjustable gas block.
With the lo-pro PRI version, I usually shut the gas completely off, then back the screw out 1/4 to 1/3 turn, using a dab of Rocksett on the screw threads (and allowing it to dry). Doing this will make you think that there's no way the weapon will function, but that's what works for me.
I would like to see 6.5 barrel makers use smaller gas ports on midlength systems, but maybe my experiences are unique...
