Choosing the Right Bore-tip® Size

Choosing the Right Bore-tip® Size

Choosing the correct Bore-tip® size is important for effective firearm cleaning. The right size helps provide proper bore contact, better solvent control, and more consistent cleaning performance.

Swab-its® Bore-tips® are reusable foam bore cleaners designed as a cleaner, lint-free alternative to traditional jags, patches, and bore mops. They are available in popular rifle, pistol, and shotgun sizes to help match your firearm’s bore diameter.

Quick Answer: Choose the Bore-tip® size that matches your firearm caliber or gauge. A properly sized Bore-tip® should fit securely in the bore, make consistent contact with the barrel surface, and move through the bore without excessive force.

How to Select the Correct Bore-tip®

1. Match the Bore-tip® to the Caliber or Gauge

Start with the caliber or gauge marked on your firearm barrel. Select the Bore-tip® size that corresponds to that caliber or gauge.

For example, a .223 Remington or 5.56 NATO rifle would generally use the .22 / 5.56mm Bore-tip®, while a 9mm pistol would generally use the .357 / 9mm Bore-tip®.

2. Choose Proper Bore Contact

A Bore-tip® should provide consistent contact with the bore surface. The foam is designed to compress and conform to the barrel, helping provide 360-degree cleaning contact.

If the fit feels excessively tight or requires too much force, stop and confirm the firearm caliber and Bore-tip® size before continuing.

3. Consider the Type of Firearm

Rifles, pistols, revolvers, shotguns, and pistol-caliber carbines may all require different cleaning approaches. Always choose a Bore-tip® size based on the actual bore diameter and firearm manufacturer recommendations.

4. Use the Right Rod or Cleaning System

Bore-tips® are designed to work with common firearm cleaning rods. Make sure your cleaning rod, adapter, and Bore-tip® are properly matched and securely connected before use.


Why Bore-tip® Fit Matters

The correct Bore-tip® size helps improve firearm maintenance by providing better cleaning contact and more controlled solvent application.

  • Improves bore contact
  • Helps distribute solvent evenly
  • Reduces lint and loose fiber contamination
  • Helps remove fouling more efficiently
  • Provides a reusable alternative to disposable cotton patches

Bore-tips® vs Traditional Jags and Patches

Traditional jags and patches can work, but they often require repeated patch changes and may leave cotton fibers behind. Bore-tips® use lint-free foam to provide controlled cleaning with fewer disposable materials.

Feature Bore-tips® Traditional Jags & Patches
Bore Contact 360-degree foam contact Depends on patch fit and placement
Lint-Free Cleaning Yes Cotton patches may shed fibers
Reusable Yes, depending on use and condition No, typically disposable
Solvent Control Excellent Varies by patch material and amount used
