GNP Defend is an American-owned company with an unusual conviction: firearm care chemistry should be held to a military standard, not a marketing one. That conviction took us to Poland — home to some of Europe's most demanding small-arms manufacturing — where every GNP Defend product is engineered and made.

We don't sell all-in-one promises. We build dedicated products that each do one job completely: a degreaser that strips, a cleaner that cleans, a foam that reaches the whole bore, a grease that holds under heat, and an oil that lubricates and protects. Clean first, then oil — that's the system, and it's behind everything we make.
