What the thread found

• Adjustable bolts rated for very high load capacity can fail unexpectedly during low-stress movements like swinging the rig into position
• The failure occurred when rotating the rig from one side to the other in a relaxed motion, not under heavy load or stress
• One bolt snapped completely while the other remained intact, suggesting a possible material defect rather than design inadequacy
• Replacement rod-end bearings are difficult to source and may have quality concerns
• A custom fixed adapter can replace the adjustable bolts when flexibility is not needed with a backpack mount system

Depends on

• The exact cause of the bolt failure was not definitively determined
• Only one incident is documented in this thread
• The replacement bolts were sourced from a third party, not the original manufacturer
• The claim about material flaws is speculative rather than confirmed through analysis
• No other users reported similar failures in this discussion
