Negative Ghostrider. I have tried swapping out followers from a 10-rd Grendel mag and put it in a 30-rd 5.56 mag. The follower fits and moves up and down; however, as Warrior Stanc pointed out, the neck on the Grendel is larger then the 5.56. The grooves on the 5.56 mag up front are a bit deeper than the Grendel to accommodate the neck size difference.
Rainier Arms sells ASC brand 25-rd Grendel mags. They are the same size as the 5.56 30-rd mags, but you can only fit some many fat cat Grendels in the same size space.
