Arms Preservation Inc. (API) rifle storage bags utilize a combination of Vapor Corrosion Inhibitor (VCI) chemistry and carefully chosen barrier packaging materials to prevent the corrosion of firearms, firearm parts and ammunition during storage for 5 years or more depending on use. API anti-corrosion storage bags are based on military tested and approved designs and are reusable and safe for all metals, finishes, optics, stocks, ammo, primers and electronics because the bags leave no residues behind and do not require the use of messy oils or greases. They have a wide range of applications that include storing hunting firearms during off-seasons, safely storing guns while away on deployment, to preserve priceless family heirlooms and storing guns that are rarely used.
