I am no expert on GPMG's but I’ve had the opportunity to own a M60 E6 for a few years and I believe the E6 is a rock solid design which really solved the common problems that the E4 experienced. Granted there will always failures due to abuse and wear that any GPMG will be limited by.
The SAW is a great tool if it's maintained properly and I feel that the mission would dictate which LMG/GPMG would get the nod as they both have pros/cons.
For static deployments I can see the value in a cumbersome T&E setups but blending my experience with Precision rifles and light weight CF Tripods that I have evolved over into deploying GPMG and Tripods with very surprising effects.
With some of the light weight Carbon Fiber Tripods being introduced today I would be curious if Mil. has ever done any R&D on a similar setup?
