Hoppe's No. 9 Gun Bore Cleaner 2oz

Hoppe's No. 9 Gun Bore Cleaner in the 2oz size is a solvent formulation trusted since 1903 for deep penetration and removal of carbon, powder, and lead fouling from rifle, pistol, and shotgun bores. This compact bottle delivers the same proven formula used by competitive shooters, hunters, and law enforcement across generations, making it an essential component in any operator's maintenance kit or range bag.

The 2oz bottlesize is purpose-built for portability and field use without sacrificing efficacy. Hoppe's No. 9 penetrates deeply into bore surfaces, loosening abrasive debris that accumulates during firing cycles—a critical factor in extending barrel life and maintaining accuracy. The liquid formula wicks into tight spaces where dry patches alone cannot reach, dissolving stubborn carbon deposits that compromise ballistic consistency. The distinctive odor profile serves as a practical indicator of bore condition and cleaning progress, helping users confirm thorough saturation during the cleaning process.

This solvent works across all caliber types and bore diameters—from .22 rimfire through large-bore rifle calibers and shotgun gauges. Shooters conducting intensive range sessions, duty weapon maintenance, or post-deployment cleaning routines rely on Hoppe's No. 9 for reliable fouling removal without requiring extended soak times. The compact 2oz format fits easily in range boxes, duty bags, or field maintenance kits, making it ideal for shooters who demand consistent bore condition management without the bulk of larger containers.
