What size barrels are these Kleenbore P206 patches designed for?

The Kleenbore P206 patches measure 4 inches by 4 inches and are specifically engineered for large-bore applications such as 10-gauge and 12-gauge shotguns, as well as 37mm and 40mm launcher barrels. They will jam or bunch excessively if forced down smaller rifle or handgun calibres.

What material are these patches made from and how many come in a pack?

Each pack contains 25 precision-cut patches made from 100% absorbent cotton flannel. This soft, non-abrasive material maximizes the absorption of bore cleaners, solvents, and lubricants while effectively lifting heavy fouling and plastic wad residue without damaging your barrel's interior.

What accessories pair well with the Kleenbore P206 patches for 12-gauge maintenance?

To get the best results when cleaning your 12-gauge shotgun, pair these 4-inch patches with a dedicated large-bore slotted patch holder or jag, and use them alongside the Kleenbore A186 Phosphor Bronze Bore Brush for thorough scrubbing before final dry-patching.

Shotgun Cleaning Patches - KleenBore P206

The KleenBore Super Shooter 4" Big Bore Shotgun Cleaning Patches (model P206) are heavy-duty, pre-cut fabric consumables designed for swabbing, solvent application, fouling removal, and dry-patching large-diameter firearm barrels. Manufactured in the USA from 100% precision-cut cotton flannel, these patches provide a non-abrasive, high-surface-area barrier that carries out heavy powder residue, plastic wad fouling, and lead deposits without damaging smoothbore or rifled surfaces. Sized specifically for large bores, they deliver the necessary wall-to-wall bore contact when paired with shotgun jags, slotted tips, or mops.

Key Features

100% Cotton Flannel Construction: Woven from pure cotton flannel to maximize the absorption of bore cleaners, synthetic solvents, CLPs, and rust preventatives.
Non-Abrasive Debris Removal: Traps and extracts heavy plastic wad fouling and burnt powder residue without scratching or abrading barrel walls.
Big Bore Coverage: Pre-cut 4-inch square geometry eliminates the need for field trimming while providing complete circumference contact inside wide-diameter barrels.
Chemical Compatibility: Safe for use with standard petroleum-based solvents, bore cleaners, and synthetic firearm oils.

Who is the Kleenbore 4" Cleaning Patches 25 Pack To Suit Big Bore Shotgun for?

Australian Clay Target Shooters — Requires 4 inches x 4 inches (10.16 cm x 10.16 cm) square cotton flannel patches to effectively trap and sweep out heavy plastic wad fouling and powder residue across high-volume 12-gauge shotgun barrels.
Hunters and Primary Producers — Relies on 100% precision-cut cotton flannel big bore cleaning patches measuring 4 inches x 4 inches to apply rust preventatives, oils, and bore solvents across large-diameter 10-gauge and 12-gauge work shotguns.
Launcher Operators — Uses 4-inch square cleaning patches that provide the necessary material surface area to swab and clean oversized 37mm and 40mm launcher barrels without requiring multiple stacked smaller patches.

Less suitable for: Small-to-mid bore rifle and handgun calibres; running a 4-inch patch down .22 through .45 calibre barrels will cause excessive bunching and jamming, requiring smaller dedicated patch sizes (such as 1-1/4" to 2-1/4" square patches) designed specifically for smaller bore diameters.
