Have a chance to grab one of these for next to nothing from someone and was curious if anyone had any first hands experience with them.

I have a LBT modular assault pack I was wanting to attach to the back molle, but was curious if the weight of a 3L hydration bladder and hunting gear like a LRF, tripod hanging off the side straps would be too much for the vest and cause it to pull the rear down and making the front of the vest want to come up towards my head/neck; or would it be fine?

I'm under the impression that the LBT MAP and this may have been made to be used together (Or I can be totally wrong). Didn't want to try and set this up as a fairly slick hunting rig with the MAP, only for the MAP to basically make the vest flop around or ride really weird.

Thanks
