The questions on the amazon page say it will hold AK magazines, and generally (but not 100%) gear that holds AK magazines will hold nerf magazines. If it doesn't, it should definitely hold at least SOMETHING from this nerf-related list:
And then you can find pouches that *will* hold nerf mags and attach them to the molle.
Thank you god, ok finally, exactly the answer I needed. Thank you SO much, I will proceed with getting this rig, because all of those things are something i could use. Btw, I will say for anyone who does see this page, the mag carriers I am using are called FastMags, they are double stacked 7.62 holders, now I won't disclose where you can get them, since the price I am getting them at is really cheap. Look on aliexpress for the single carriers, they are MOLLE compatible and are basically a better version of the NMAG system, don't buy that junk, this is literally half the price and is the same exact thing.
Edit:and this should be pinned somewhere, I think it's useful for the community where to get a cheap loadout, this tread has established that the above vest is highly modular and useable. Then I said basically the best option out there for mag holsters, if any of you guys need a good loadout, use this system. Most people of course recommend the above Nstar vest, but for anything more than 12 mags aka any rig that runs a rapidstrike or hyperfire you are going to want these things..
