The links that MGA made for the 6.8 could probably be stretched just a hair the same way we stretched M27 links for 5.45 (which worked well). I have some of those links - but I am pretty sure they went through few more iterations since then, I need to call them and get some of the newest ones to play with.
But then you have to mod the feed tray a bit, no big deal - but you really need to increase the height between the feed tray and the top cover since you made the cartridge "fatter". Then you need to change the geometry of the feed lever for the increase in belt pitch forced by the increase cartridge diameter.
This is why I am kit-bashing an RPD onto my SAW, much faster fabrication time so I can get shooting and prove a concept. As a civilian shooter - I am also fine with non-disintegrating belts, much easier to recover.
