Pro-Shot 20R Bore Brush for 20/204 Cal Rifles - 5-40" Thread, Brass Core with Bronze Bristles

The Pro-Shot 20R bore brush is purpose-built for serious rifle maintenance on .20 and .204 caliber firearms. Whether you're prepping between competition rounds or running a hunting rifle through a thorough cleaning cycle, this brush delivers the kind of brass-core construction and bronze bristle durability that competition shooters have relied on for decades — a track record that includes multiple world records. The 5-40" thread fits standard cleaning rod connections, making it a straightforward swap into your existing rod setup.

What sets the Pro-Shot 20R apart is its oversized design. That extra material isn't marketing talk; it's practical engineering. Oversizing extends brush life under the repeated, aggressive use that comes with competition shooting and frequent deep cleaning. The brass core won't damage your bore no matter how hard you scrub, and the bronze bristles are stiff enough to cut powder fouling and carbon without being so coarse they cause wear.

Benchrest shooters have used Pro-Shot brushes long enough that the brand is almost synonymous with precision rifle cleaning. If you're running a .20 or .204 rifle and want a brush that'll outlast the ammunition, this is a straightforward choice.

Frequently Asked Questions

Will this brush fit my cleaning rod?

The Pro-Shot 20R has a 5-40" thread, which is the standard connection for most rifle cleaning rods. Verify your rod uses this thread size before ordering.

Can I use this brush on both .20 and .204 caliber rifles?

Yes. This brush is sized for both .20 and .204 caliber bores.

Why is it oversized?

The oversized design extends the brush's working life, particularly during the frequent, intensive cleaning cycles that competition shooters and serious hunters demand. More material means the bristles last longer before wearing down.

Will the brass core or bronze bristles damage my bore?

No. Brass and bronze are softer than steel rifle bores and are specifically chosen for bore brushes because they clean effectively without causing wear or damage.
