KleenBore P206 Super ShooterBig Bore Shotgun/37/40mm Launcher4" 100% Cotton Flannel 25 Per Pack

The Kleen-Bore P206 Super Shooter big bore shotgun patches are engineered for serious shooters who demand quality cleaning supplies sized for their heavy artillery. Each pack contains 25 patches cut to a 4-inch square—the right dimension for bore swabs in 12-gauge shotguns, 37mm, and 40mm launcher systems. Built from 100% cotton flannel, these patches deliver the absorbency and durability you need when running a wet patch downrange to remove powder fouling, copper, and lead buildup without shredding or leaving lint behind.

If you're running a shotgun hard—whether hunting waterfowl, sport shooting, or working with larger-bore systems—cheap patches fall apart mid-bore and leave you frustrated. Flannel patches grip your cleaning rod properly, hold solvent or oil effectively, and break down only after they've done the job. Twenty-five patches per pack means you've got enough for multiple deep cleans without rationing, and the bulk count keeps your cost per session low.

Kleen-Bore has been the gunsmith's go-to for decades because they understand that bore cleaning isn't a sales pitch—it's maintenance that directly affects accuracy and gun longevity. These patches aren't flashy; they're just reliable, well-made cotton that performs when you need it.

Frequently Asked Questions

Will these patches work with 12-gauge shotguns?

Yes. The 4-inch flannel patch is sized for big bore shotgun cleaning, including 12-gauge systems. The flannel grips your cleaning rod and rod tip securely while holding solvent and oil for effective bore swabbing.

Are these patches suitable for 37mm and 40mm launchers?

Yes. These patches are specifically engineered for both shotgun and 37/40mm launcher bore diameters, making them a versatile choice if you maintain both types of systems.

How many patches should I expect from one pack?

Each pack contains 25 patches, giving you multiple complete cleaning cycles before needing to reorder.

What's the advantage of flannel over cheaper patches?

Cotton flannel resists shredding and linting during the cleaning process, meaning you get a clean bore without leaving fibers behind. The absorbency also allows the patch to hold solvent or oil effectively throughout the stroke.
