The Kleen-Bore A177N is a .22/.223/5.56mm rifle bore brush designed for shooters who take their rifle maintenance seriously. Built with nylon bristles and an 8-32" thread, this brush handles the fouling and buildup that accumulates in smaller-caliber rifle barrels during regular shooting and hunting. Whether you're a competitive shooter keeping your AR-15 running clean, a varmint hunter maintaining your .223, or a rimfire enthusiast caring for a .22 rifle, this brush removes carbon, copper, and powder residue without the risk of scratching your bore.
Nylon bristles are gentler on barrel steel than steel or brass alternatives, making this brush a solid choice for hunters and shooters who want effective cleaning without worrying about accelerated wear. The 8-32" thread fits standard rod adapters, so it integrates seamlessly into most cleaning rod setups you already own. It's a no-fuss, straightforward tool that does one job well: getting the inside of your barrel ready for the next shot.
Keep one of these in your range bag or cleaning kit. Bore brushes wear out with use, and having a fresh brush on hand means you're never tempted to skip barrel maintenance between outings. For hunters and shooters who rely on consistent accuracy, a clean bore is non-negotiable.

Frequently Asked Questions
Will this bore brush work with my AR-15?
Yes. The A177N is designed for 5.56mm rifles, including modern AR-15 platforms. The 8-32" thread is standard for most rifle cleaning rod systems.
What's the difference between nylon and steel bore brushes?
Nylon bristles are gentler on barrel steel and are a good choice if you're concerned about accelerated wear from more abrasive materials. Steel or brass brushes are more aggressive; nylon offers a balance of effective cleaning and bore preservation.
Is this brush compatible with my cleaning rod?
If your cleaning rod adapter accepts 8-32" threaded inserts, yes. This is the standard thread size for most .22 and .223 rifle cleaning setups.
How often should I replace my bore brush?
Bore brushes wear out with repeated use. If bristles are matted, missing, or no longer making contact with the barrel, it's time for a fresh brush.
