The KleenBore M16B Military Style Bore Brush is purpose-built for deep cleaning .223/5.56mm rifle barrels on AR-15s, M16s, M4s, and other modern sporting rifles that see serious trigger time. If you run an MSR hard—whether at the range, in the field, or downrange—this brush is engineered to handle the punishment and deliver a thorough scrub down the bore.
What sets the M16B apart is its construction: phosphor bronze bristles paired with a core wire that's looped directly through the brass coupling for maximum durability under heavy use. The military-style #8-36 thread is the real deal, not a compromise. It's the same specification found on mil-spec cleaning rods, which means compatibility is built in from the factory.
One thing to note: the #8-36 coupling is not a standard commercial thread, so this brush won't simply screw onto most consumer cleaning rods. It's designed to pair with KleenBore's military-pattern rods—like those included in their Classic Rifle Kits, Field Pack Kits, and the All Caliber Vinyl Pouch Rod Set (#S-170). If you already own a KleenBore multi-section rifle rod, you're good to go. If you're building a cleaning kit from scratch, pair this with a compatible rod and you've got a professional-grade setup that'll serve you for years.
Made in the USA, this is the kind of detail-oriented tool that separates a casual shooter from someone serious about rifle maintenance.
| Caliber | .223/5.56mm |
| Thread Type | #8-36 (military-style) |
| Bristle Material | Phosphor bronze |
| Suitable For | AR-15, M16, M4, and similar modern sporting rifles |

The #8-36 military-spec thread will fit KleenBore multi-section rifle rods, including those in their Classic Rifle Kits, Field Pack Kits, and the All Caliber Vinyl Pouch Rod Set (#S-170). It will not fit most standard commercial cleaning rods, which use different thread sizes.
This brush is designed for .223 caliber and 5.56mm rifle barrels, making it ideal for AR-15s, M16s, M4s, and other rifles chambered in those cartridges.
Phosphor bronze bristles are harder than nylon but softer than steel, allowing them to scrub fouling and carbon buildup effectively without scratching or damaging the rifling inside your barrel.
Yes. The core wire is looped directly through the brass coupling, which is a military-style construction method designed to withstand repeated heavy use.
