you know you can take m16 mag pouches and stick 14 mags in them, just sideways instead of fore and aft- that way you don't have to deal with the heavy canvas of the 56 series-- also the later or last issue of the fn kit- those are nice since they have the pull up tab, but might not always fit- that's because of the welded on button at the rear of the mag- if u can, take your mag with you when you're buyin g surplus.
