Re: ??? about the 6.8 spc round
from what I read you can use the 5.56 mags but you need to change the followers out and possibly bend the feed lips a tad. So if you have a ton of mags already you could save money by just converting a few.
If you're thinking about going that route I would suggest checking out the 6.5 Grendal round also. It looked on paper to have an edge on the 6.8 from what I remember.
