Frequently Asked Questions
Can this kit be used with shotgun gauges other than 12 and 20?
This kit is specifically designed and sized for 12 gauge and 20 gauge shotguns. The bore brushes, cotton mops, and felt patch savers are all calibrated for these two gauges only. For other gauges such as 28 ga or .410 bore, you would need a separate dedicated cleaning kit sized appropriately to avoid damaging your bore or getting an inadequate clean.
Are the brass rods safe for all shotgun barrel types, including ported barrels?
Yes, solid brass is a bore-safe material that is softer than steel, meaning it won't scratch or damage your shotgun's barrel, choke threads, or internal surfaces — including ported barrels. Otis Technology designs their rods to flex and follow the bore rather than force a rigid straight path, reducing the risk of damage during cleaning.
What's the difference between the bronze bore brush and the cotton mop, and when should I use each?
The bronze bore brush is used first to aggressively scrub carbon fouling, plastic wad residue, and lead deposits from inside the barrel. Once the heavy fouling is loosened, the cotton mop — used with a quality solvent or oil — is run through to collect residue and apply a protective coating. Using them in sequence gives you a thorough clean and leaves your bore properly conditioned for storage or the next range session.
