Right now there is a complete Multicam battle belt rig for sale.
Set up to carry 3 18-round mags, a small pouch for loose darts and a hammerstrike holster.
This is a used rig, and is sold as is (it's mostly made up of prototype parts, and has served me well, but I have so much extra gear it's not needed any more)
Size Medium, includes adjustable inner belt. Would fit 28-36" waist, comfortably.
Asking $185 including US shipping. Only one available at this price. Message on Facebook, or email if you're interested.
