This mag pouch was designed to carry a reserve supply of ammunition for the M3 and M3A1 submachine gun used in World War 2 through the Vietnam War. The original cotton duck was replaced with nylon duck after 1972 so this particular pouch is from the late Vietnam War era.

  • Size: Approx. 10″ x 5″ x 2.75″ (5.5″ x 10.75″ flat)
  • Fabric: Olive green nylon duck treated with water-repellent

NSN: 8465-00-705-2438

Fun Factoid: The original M3 was nicknamed the ‘Grease Gun’ because it looked so much like a mechanic’s lubrication tool.

    Purpose Built

    I am working on an airsoft kit based on my great grand father's position as a tank recon commander in WWII and as such I needed an M3A1. This pouch holds six magazines comfortably for the M3 and I suspect it would hold other similar submachine gun magazines just fine as well!

    I bought this to hold some SMG mags, not necessarily for the M3. Looks brand new and works as I'd hoped.
