Great video and report. I would have guessed the bolt carrier would have had more rearward movement with the gas key screwed closed. Cam pin wear wouldn't worry me at all after watching the little rearward movement created with the adj gas screw screwed shut. With the screw opened to optimal setting the cam pin stress would be nil. I'm still a little concerned if the adj gas key screw wont unscrew during recoil . Only time and use will tell. I would heat the gas key screws if they showed resistance when trying to remove them. They could have had red loctite put on them. Solving the pinned flash hider problem was the main reason I was looking at the adj gas key solution. Keep us informed on any changes. Thanks again for your report.
