Hey Matt,
I was thinking about your comment that the M416 trailer used 3/4-inch rod instead of the 1/2-inch rod on the M100.
You can kind of see in my photo album that the loops are somewhat deformed, most likely from being used over the years. Seeing as the M100 and M416 both have about the same payload and prime mover, my bet is they upgraded to 3/4-inch rod on the M416's for heavier duty and less deformation, more safety margin.
I believe these loops are primarily for sling lifting a pay-loaded trailer aboard ship and less as a tie-down, although it does both.
Just speculating on both points. Well before my time. Can't find any published USMC evidence about the modification at all.
Yeah, I would imagine so - they probably saw the need for the upgrade from 1/2 - 3/4" in the M416 and included that upgrade in the B1. I figured that they were mainly used for lifting onto ships but tie down point as a secondary use. _________________ Matt

Hi Matt,
I measured the inside diameter of the loops and can confirm 3 inches, including paint. _________________ Ron D.
