Thats a lot of ammo???
107 30 round mags, assuming all are full, that is 3,210 rounds. All are AR plateform firearms, ammo appears to be all 5.56.
Pistols appear to have mags.. 5th row of magazines appears to be interupted with some pistol mags. 17 pistols, smiths, glocks, rugers mix, average 14 rounds per mag, Probably 250 rounds.
You seriously consider that a lot of ammo?
