The ZCORR Vacuum Tactical Weapon Bag was designed to protect modern tactical rifles or other firearms with large attachments from corrosion and general contamination. The vacuum valve and 100% water proof and airtight zipper closure allow this bag to maintain its enhanced preservation qualities for extended periods of time in multitudes of environments. Depending on a firearms overall height optics, lights, and magazines may remain mounted and are unaffected by VpCI molecules. As always, optics should be stored with caps on. The Tactical Weapon Bags are the most convenient storage and preservation solution for AR platform rifles, AKs, and other modern repeating rifles.
