GNP Defend Gun Oil
Lubricates and protects — with the paperwork to prove it. Military-tested on eight service firearms: 10,000 rounds fired, zero corrosion. Rated stable from −76°F to +482°F (manufacturer specification). Clean first, then oil.
GNP Defend Gun Cleaner
Removes carbon, powder residue, copper, and lead — without the chemical cloud. Water-based, non-toxic, ammonia-free, and odorless, so you can clean at the kitchen table. The same cleaner used throughout our 10,000-round military endurance test. Clean first, then oil.
GNP Defend Bore Cleaning Foam
Sprays in, expands to fill 100% of the bore, and clings while it works. Ten to fifteen minutes of dwell time dissolves carbon, copper, lead, and zinc — so the patches do the work instead of your scrubbing. Water-based, ammonia-free, no odor.
GNP Defend Optic Cleaner
Clear glass is accuracy. GNP Defend Optic Cleaner lifts smudges, dust, and oily residue from scopes, red dots, and binocular lenses for a crisp sight picture. Compact bottle, range-bag ready — because a $1,000 optic deserves better than a shirt sleeve.
