✓ High-Memory Bristles: Designed to spring back to shape even after hundreds of passes through the barrel.
✓ Precision-Fit Threads: Industrial-standard threading (8-32, 5/16-27, etc.) for a secure, wobble-free fit on all cleaning rods.

✓ OEM/ODM Branding: Custom stem coatings (Black/Silver) and private label packaging available for your brand.
The Phosphor Bronze Gun Cleaning Brush is the workhorse of any serious firearm maintenance kit. Unlike soft copper or cheap nylon alternatives, our phosphor bronze bristles offer the ideal hardness to strip away stubborn lead, copper, and carbon fouling while being significantly softer than the steel of your barrel, ensuring zero damage to the rifling. Whether you are a professional armorer or a retail brand looking to expand your SKU list, these brushes set the benchmark for cleaning efficiency.

Q1: How often should I replace these bronze brushes?
Answer: While our phosphor bronze bristles are built for longevity, they will eventually lose their stiffness after hundreds of passes. For professional-grade maintenance, we recommend replacing them when you notice visible bristle fatigue or when the brush no longer provides a snug fit in the barrel.
Q2: Do you offer custom thread sizes for specific countries?
Answer: Yes. We understand that international markets use different thread standards (e.g., US 8-32 vs. Metric threads). We can manufacture the threaded stem to meet your specific regional technical requirements.
Q3: What is the MOQ for unbranded bulk brushes?
Answer: For unbranded bulk brushes (packaged in simple protective bags), we can support smaller wholesale orders to help your business get started. For individually tubed or carded brushes, our MOQ typically starts at 1,000 units.
