This makes me sad - seems like the gas port might not be perpendicular to the friggin bore's axis...

gas block resting very lightly on a pic rail attach nut - prolly bad from a bbl whip perspective

lol - the hotel might not be too happy with me if they knew I was playing gunsmith in the room (I'm on an extended TDY - shipping all this stuff home might impute me driving back to MI vs. flying home (which is fine - I'd rather have the distraction of being intellectually stimulated vs. drowning muh sorrows in beer/whiskey or netflix)). I did, however, check with them to ensure that having weapons in the rooms were allowed. It is.

This is the gas port on my 16" 5.56 Franken AR (looks a hell of a lot cleaner than the port on my Grendel...):

Getting good results at the range with the 6.5G in its current state (hunting scope, old-eyes me shaking the cob-webs loose, etc.) with factory ammo (123gr Hornady AG)

MH:
Looking at your magazine picture, I would seat the bullets deeper and get the tips off the inside front of the magazine. With the Grendel you are generally limited by the magazine length so forget about seating a bullet X amount off the lands unless the magazine accepts that length.
