Bore Tech Extreme Grease HD 10cc Triple Based Synthetic Gun Grease Syringe

The Bore Tech Extreme Grease HD is an ultra-tacky, triple based synthetic blend formulated specifically for superior firearm operation. Packaged in a convenient 10cc syringe applicator, this heavy-duty firearm grease is built to handle the punishing friction, heat, and wear placed on critical wear surfaces every time you cycle the action.

Extreme Grease HD is rated for an extreme operational temperature range of -85°F to +700°F, remaining stable and non-gumming in arctic cold and brutal high-heat conditions alike. Its advanced synthetic formula is engineered to penetrate metallic and polymer surfaces, delivering long-lasting lubrication exactly where it is needed. The grease clings where applied without running or throwing off, so it stays on the part through recoil and rapid cycling.

This grease is purpose-built for the high-stress contact points inside a firearm. It is ideal for locking lugs, frame rails, hinge pins, and camming mechanisms, the very surfaces where conventional oils tend to migrate away or burn off under sustained fire. Whether you are maintaining a semi-auto pistol, an AR-platform rifle, a bolt-action hunting rifle, or a shotgun, Extreme Grease HD delivers the heavy-duty protection these parts demand.

Beyond its performance, the formula is eco-friendly. The precise 10cc syringe lets you drop the grease exactly onto the contact surface with no mess or waste. Whether you are performing routine maintenance, building a new firearm, or chasing down function issues caused by inadequate lubrication, this is a workshop staple that earns its spot on the bench.
