The Proshot 6mm-7mm Square Patches 500 Pack (manufacturer model 13/8-500) contains pre-cut firearm bore cleaning patches designed for routine maintenance, carbon stripping, solvent application, and bore drying. Manufactured from 100% USA-grown cotton flannel, each patch measures 1-3/8 in × 1-3/8 in (approximately 34.9 mm × 34.9 mm) and features a double-napped weave on both sides. This raised fleece texture absorbs bore solvents and traps fouling without causing mechanical abrasion to barrel rifling or crowns. Sized specifically for 6mm through 7mm bore diameters, these patches interface with standard spear-tip jags and slotted patch loops to provide consistent radial pressure against lands and grooves.

Key Features

• Double-Napped Cotton Flannel: Raised fleece nap on both sides maximizes solvent absorption and lifts carbon, copper, and debris during jag passes.
• Consistent 1-3/8 in Pre-Cut Sizing: Eliminates uneven hand-cutting to ensure uniform friction and bore-wall contact across 6mm to 7mm barrels.
• Non-Abrasive Barrel Protection: 100% cotton construction protects barrel rifling, lands, grooves, and crowns from wear during cleaning cycles.
• Hardware Interface Compatibility: Sized for direct use on standard spear-tip cleaning jags and slotted patch loops.

Who is the Proshot 6mm-7mm Square Patches 500 Pack for?

• Precision rifle reloaders and benchrest shooters — Requires the uniform 1-3/8 in × 1-3/8 in square dimensions to maintain consistent jag compression when stripping copper and carbon from 6mm Creedmoor and 6.5mm Creedmoor match barrels across a 500-count supply.
• Hunters and target shooters — Uses these firearm bore cleaning patches sized for 6mm through 7mm bore diameters to clean and dry .270 Win and 7mm hunting rifles without risking crown or rifling abrasion.

Less suitable for: Firearm bores under 6.0 mm (such as .17 to .22 calibres), where a 1-3/8 in square patch is too tight and can jam on standard jags, requiring smaller 3/4 in or 1-1/8 in square patches; and bores over 7.0 mm (such as .30 calibre to .38 / 9mm), where this dimension provides insufficient radial compression, requiring larger 1-3/4 in square or 2 in round patches.
