Basically you get any extra rail you have from accessories or a crossfire and attach an Nf ammo holder on the top any way you can (glue, velcro). I've had one for a while on my minimized NF and it works well and it doesn't have to have permanent bulk added to it since it's detachable and kinda looks cool to me. And you could also put it on any other gun even if they aren't minized just for a little extra ammo. Plus if you put velcro to attach it you could get multiple ammo holders and reload the ammo quickly (weird).
A few picture links to what mine looks like.

Shit, I better have not been late on this.
