if its mp5 mags ur looking to hold order this, i was having the same dillema, got 6 mags to carry and 6 mag holders would take up a lot of molle space
i ordered this
http://www.flecktarn.co.uk/ustmp5nx.html
from that site, came to just under $30 CAD with shipping
the product is great, holds 6 mp5 mags tightly, 2 per slot
rugged design and feels like it will last a long time, good quality product
came to my door in under 2 weeks
*edit* was the only mp5 mag holder i could find online that would hold double mp5 mags per slot
