Need a simple, waterproof solution for small accessories or parts? Here's your answer! These U.S. Military Surplus Waterproof Ammo Bags were originally used during the Vietnam War as part of the Chieu Hoi Program to encourage the Viet Cong to give up and surrender. Each plastic bag comes printed with a "surrender" message and will fit an M16 magazine or similar. Great for gunsmithing parts or small accessories, too. Plastic Ammo Bags are brand new, never issued but are a cool collectible for history buffs.
