Brownells Standard Line Brush, Nylon, .40 Caliber Pistol, 12 Pack

A .40 caliber pistol bore brush is one of those consumables that disappears fast when you shoot regularly and clean conscientiously. Brownells Standard Line brushes come in a 12-pack so you've got spares on hand and can keep multiple guns in rotation without waiting for a brush to dry between cleanings. Unlike cheaper brushes that can wear out or degrade when exposed to aggressive bore solvents and cleaners, these nylon bristles hold up to modern copper and bronze-removing chemicals without softening or shedding fibers into your barrel—keeping accuracy intact.

The real difference is the shank construction. These are one-piece, looped and wound steel—not two strands twisted together and chopped off. That solid design means the bristles stay evenly anchored and won't separate or fray under pressure. At 2⅛ inches long with a standard 8-32 thread, they'll work with any rod that accepts that size, making them a reliable drop-in for your pistol cleaning kit at the range or bench.

Whether you're a volume shooter, competition participant, or just methodical about maintaining your .40, stocking a dozen of these eliminates the frustration of hunting for a brush mid-cleaning session. They're sized right for handgun barrels and built tough enough to earn their place in your gun maintenance rotation.

Frequently Asked Questions

What thread size does the .40 caliber Brownells brush use?

The .40 caliber model uses a standard 8-32 thread, which is the most common size for pistol-length cleaning rods.

Will these nylon brushes work with solvent strippers and aggressive bore cleaners?

Yes. Nylon bristles are specifically designed to withstand modern copper and bronze-removing chemicals without degrading, softening, or scratching your bore.

Why does the 12-pack make sense for regular shooters?

Brushes get wet with solvent and need drying time between uses. A 12-pack lets you keep a fresh, dry brush ready for the next cleaning without waiting, plus spares for backups and other .40 pistols in your collection.

Is the one-piece shank construction better than twisted designs?

Yes. One-piece looped and wound shanks keep the bristles evenly anchored and prevent fraying or separation that can occur with two strands twisted and cut off.
