There appears to be an interference issue with the bipod rail and the neck of the carbon fiber bottles. I noticed the rail started to dig into the bottle when I removed my bottle to tune the regulators (leaving a ring around the neck)!
The clearance problem appears to be the spacing between the lower/rail and the rifle, when the forward screw (that goes through the trigger guard) is snugged down. You can back it out some and possibly have clearance, but I decided to grind the inner rail sections that were digging into my bottle. Here, I did a test with a Sharpie after having removed some of the anodization:
Reinstalled the bottle and removed it once more, which left me with this last spot to grind down:
Not sure what FX is going to do to remedy this one
