CLENZOIL Field & Range 50 Caliber Cobra Bore Cleaner | Gun Barrel Cleaning Tool for 50 Cal 50ae | Brass Brush Embedded in Cotton Bore Rope | 50 Cal Muzzleloader Bore Rope

Designed exclusively for .50 caliber rifles and muzzleloaders, this cleaning system maintains precise bore contact throughout each pass. Unlike oversized or undersized universal tools, the rope fits snugly against the bore surface, removing residue more efficiently with fewer strokes and ensuring consistent cleaning across the full length of the barrel.
The integrated brass bore brush is permanently woven into the cotton rope, creating a seamless, dual-action cleaning pass. As it’s pulled through the bore, the brush agitates fouling while the trailing cotton braid captures and removes debris—eliminating the need for jags, rods, or patch systems, and simplifying your cleaning routine.
Crafted from high-density cotton, the rope is non-abrasive and engineered to trap fouling without damaging rifling. Fully washable and reusable, it withstands repeated use, offering long-term performance for black powder shooters and high-volume marksmen who rely on consistent bore care between sessions.
Each kit includes 0.25 oz of Clenzoil Field & Range CLP, a proven cleaner, lubricant, and protectant. The formula allows for immediate bore conditioning after fouling removal, without switching to secondary products. It’s safe for metal, polymer, and wood—compatible with a wide range of firearm materials.
This system is compact and field-ready, requiring no assembly, alignment, or accessories. It rolls up small for storage in a hunting pack, range bag, or bench kit, enabling quick, effective maintenance whether you’re in the field or at the range. The single-piece design maximizes portability without sacrificing performance.
