[QUOTE="CMP70306, post: 1733074, member: 36999"] In this case it wasn’t so much they got the headspace wrong, they made the decision to set the headspace so that the top of the Barloc closes and didn’t notice the POI issue in their testing. It wasn’t until the barrels were out in customers hands that the issue became apparent. A guy over on snipers hide fixed his by running a finish reamer in an additional .007” which allowed him to tighten the barrel enough to stop the POI shift. I considered it but I generally like the Barloc and would prefer to keep it. Based on my calculations I need to back the barrel off approximately 1/16th of a turn to match up with my go gauge which corresponds with a shim approximately .004” thick. Assuming that some additional thickness is required to ensure proper preload on the system then the .007” difference as explained above seems to be the ideal for fixing the issue. [/QUOTE]
