3. Should I choose a universal kit or a caliber-specific kit?

Universal Gun Cleaning Kits:

  • Great if you own multiple firearms.

  • More cost-effective in the long run as you add calibers.

  • Convenient all-in-one solution.

Caliber-Specific Gun Cleaning Kits:

  • Best for owners of one main firearm type.

  • Usually cheaper upfront.

  • More streamlined and simple to use.

4. What is “breech-to-muzzle” cleaning and why does Otis focus on it?

Breech-to-muzzle cleaning means pulling a cleaning tool through the barrel from the chamber end (breech) toward the muzzle. Otis’ flexible cable system makes this possible.

Why it matters:

  • Protects the barrel crown.

  • Follows the natural direction of bullet travel.

  • Helps remove debris rather than push it deeper into the bore and action of your firearm.
