Description
Bore Tech built Friction Guard XP for folks who put real rounds through their guns and expect the lubrication to keep up. It's a synthetic blend of oils, penetrants, and friction-reducing additives paired with strong rust and corrosion inhibitors. What sets it apart is how those additives work at the surface, sinking into the metal's pores and bonding to form a film-strength layer that keeps moving parts sliding smooth and protected against everyday wear.
The temperature range is where this stuff earns its keep. Bore Tech rates it from -100°F to 600°F, which means it won't gum up and turn sticky when the cold sets in, and it won't cook off during rapid or full-auto fire. That's a big deal if you're hunting in brutal weather or running a rifle hard at the range. It's also formulated to meet and exceed MIL-PRF-63460E requirements, so this isn't a lightweight hobby oil.
Where Friction Guard XP Really Shines
This is a true do-it-all lubricant for the metal that moves and rubs. Wipe or dab it onto barrels, trigger assemblies, actions, bolts, pistol slides, and any other moving metal parts, then cycle everything a few times to spread it evenly. It stays put without attracting dust and grit, and it actually helps repel fouling while you shoot, so cleanup down the road is less of a chore.
Rust Protection That Goes the Distance
Beyond lubrication, Friction Guard XP lays down a micro-thin barrier film that fights moisture and neutralizes corrosive residue. It has held up past 100 hours in the ASTM B-117 salt spray test, which is serious rust resistance. A light coat before your gun goes into the safe keeps conditioning the metal during storage, and it's rated safe to run inside the bore for long-term protection too. Just remember to pass a dry patch through the bore before shooting. Made in the USA, in a handy 4 oz twist-cap bottle that dispenses right where you want it.

Frequently Asked Questions
Can I use Friction Guard XP inside the bore?
Yes, Bore Tech says it's fine to run inside the bore to protect against rust and corrosion for extended storage periods. Just wet a patch or mop and pass it through until a light coat is present. Before you head out to shoot, run a dry patch through to clear any residue.
How is Friction Guard XP different from Bore Tech's Shield XP?
Friction Guard XP is a lubricant meant for internal use like rifle bores and on moving parts, and it also protects against rust and corrosion. Shield XP is designed for the exterior of firearms as a rust and corrosion preventive and is not a lubricant. If you need something that both lubricates and protects, Friction Guard XP is the pick.
Will this gun oil hold up in extreme cold or heat?
It's rated for a -100°F to 600°F operating range, so it won't turn sticky and gummy in deep cold or burn off during rapid and full-auto fire. That makes it a solid choice for cold-weather hunts and hard range days alike.
Does Friction Guard XP attract dust and dirt like some oils?
No, it's formulated to stay put without pulling in dust and debris, and it actually helps repel fouling while you shoot. That means less gunk building up and an easier cleanup afterward.
