The Single 556 Shorty is designed to hold one 30 round 5.56mm AR15 magazines. It is specifically sized for thicker magazines, so most polymer mags will fit. It is laser cut from Cordura laminate, making the pouch very abrasion resistant while still being lightweight. The pouch is lined with mil-spec loop and it includes a Kydex magazine insert. The bottom of the pouch has a centred drain hole to allow water and any other particulate to exit. The back of the pouch has a built in mounting system, compatible with PALS webbing. Weighs only 70g and is 3.75” tall, ideal for use with shorter magazines.
