The MDT Nanoguard Gun Protector is the second step in our three-part maintenance lineup, designed to protect your firearm from rust, wear, and the elements over time. Leveraging tungsten disulfide nanoparticles—originally developed to reduce friction in heavy mining cables—this formula bonds to metal and polymer surfaces, forming a long-lasting, hydrophobic layer. It locks out moisture, reduces friction, and holds up in extreme temps and storage conditions. Whether you're storing your rifle for a season or just finished a long match, this is the layer that locks in readiness.
