I have some c7 mag holders that work great, each holds two mags and I have a pair of them, on back of my static vest. Then I have a shotgun shell belt that holds up the holster and has 25 elastic spots for 10 rds and 12ies. I'm running the tiberius single mag holder zip tied to the left shoulder strap on the vest. The single will be empty at the start and used as a place to stick mags quicky instead of trying to get them back in the c7 mag holders. I'm sure it will change up as I sort out my preferences.
As for the overlords those are pretty much wall hangers now. they'll make the odd trip back to the field for novelty use. I still can reload the mags on those almost as fast as I can swap mags in the t8.
