My Nice frame doesn't have any plastic or webbing common loops on the frame that Kifaru uses to attach the bottom of the load sling with the 3-bar sliders. Instead MR uses all SR buckles for frame attachments. Luckily, the SR buckles from MR work with the SR buckles from Kifaru, so you could easily make it work. All you would need are 2 extra sets of SR buckles from Kifaru to attach the bottom. You would push the 3-bar slider at the bottom of the cargo panel through slotted male buckles and then thread the female side onto the bottom (2) straps of the MR frame. My Nice frame came with males threaded onto the bottom straps and females sewn to the frame at the midway point. By replacing the bottom threaded males with females, you will be able to move the cargo panel between the bottom and middle frame attachment points. The width may not match up perfectly, but that won't matter too much. Then you can use the rest of the strap/buckles that come with the load sling to attach the sides and top. Should work pretty darn good.
Exo's beaver tail will work too, but it doesn't come with any compression straps. Exo uses the compression straps sewn to their frame. So, you'll need to buy at least 2 sets of compression straps or more depending on how many courses of compression straps you need. You'll also need 4 sets of SR buckles (2 sets for the top attachment and 2 sets for the bottom attachment) to make it work. All of those can be ordered from Kifaru. However, with no load or a small load, you won't be able to compress the panel down because there are no pals to move the compression straps inboard. There are workarounds for this as well if you adopt the HPG compression system or have pals sewn on.
