Specially formulated to prevent rust and protect your valuable firearms in the harshest hunting and shooting environments. MoistureGuard's Volatile Corrosion Inhibitor (VCI) technology actively penetrates into the smallest crevices to leave an invisible, long-lasting film that blocks moisture and prevents surface rust. Still provides the same superior lubrication you expect from original Rem Oil for proper weapon function and smooth operation. Pump-spray works great for treating large areas and is ideal for your firearm after a hard day in the field or at the range. Mfg: Remington SPECS: 6 oz. (177ml) plastic pump-spray bottle.
