Otis Foaming Bore Cleaner 3oz. -

The Otis Foaming Bore Cleaner 3oz. is a specialized cleaning solution designed for operators and shooters who demand efficient, thorough bore maintenance without extended downtime. Whether you're conducting post-range maintenance or field-stripping after duty, this foaming cleaner addresses a core challenge: residual fouling and copper buildup that standard liquid cleaners miss. Law enforcement and military personnel rely on Otis bore cleaners because the formula works fast and requires minimal scrubbing—critical when you need your firearm ready for immediate deployment.

The expanding foam technology is the key differentiator. Simply spray the Otis Foaming Bore Cleaner into the breech, and the foam fills the entire bore cavity, allowing chemical action to break down powder residue, primer debris, and metal fouling without manual agitation. The foam expands to contact bore walls uniformly—something brush-only or liquid-only methods cannot guarantee. This passive dwell time means you're cleaning while attending to other tasks. Once the foam has worked, pair it with an Otis Breech-to-Muzzle cleaning kit or Ripcord for final removal. The 3oz. size is compact enough for field kits and range bags, yet delivers sufficient volume for multiple bore cleaning cycles on standard rifle and pistol platforms.

This cleaner is ideal for AR-15s, AKs, bolt guns, handguns, and shotguns—any firearm with accessible breech access. Shooters running suppressed or high-round-count training sessions will see the greatest benefit, as carbon and copper accumulation accelerates with sustained fire. The Otis system is modular; the foaming cleaner works seamlessly with Otis patches, brushes, and jags, making it a cost-effective addition to an existing cleaning kit. Store the 3oz. container upright and ensure the spray nozzle is clean before sealing to maintain pressure and foam consistency across multiple uses.
