Description
The Ballistol FlexClean Bore Cleaning Rope is one of those tools you wish you'd had years ago. Sized for .25 to .27 caliber bores (6.3 to 7.2mm), it's a simple pull-through cord that gets your barrel clean fast without pulling the gun apart. Drop the brass weight down the chamber, pull it through in your shooting direction, and let the built-in balls and sponges do the work. That's the whole routine.
What makes it tick is a set of three rubber pressure balls woven into the cord and separated by sponge chambers. The balls are sized to match your caliber so they ride the full inner surface of the bore and push powder residue and fouling out the muzzle end. The sponges hold your cleaner and oil, so you can run solvent up front and a light coat of oil on the back to clean and protect in a single pass. It's a non-abrasive, brush-free design, which means no scratching the bore on a gun that just needs regular upkeep.
Where the .25-.27 FlexClean Rope Earns Its Keep
This is a range bag and hunting pack staple. Because it's compact and needs no tools, you can run it through the barrel right after your last shot, ideally while the barrel is still warm but not hot. Whether you're wrapping up a range session or field dressing gear after a hunt, it takes maybe a minute. It pairs best with Ballistol on the sponges to neutralize and lift powder residue, which is the stuff that does the most damage to a barrel over time.
Cleaning and Caring for Your FlexClean Cord
The cord and its parts are chemical-resistant and fully washable. When it gets grungy, warm water and a little dish soap brings it back, and it's built to be reused over and over. The caliber is engraved right on the brass weight and the whole thing is color coded, so you'll never grab the wrong size. It ships in a handy box with a hanging tab. Made in Germany.

Frequently Asked Questions
Do I need to take my gun apart to use the FlexClean rope?
No. The whole point of the FlexClean is skipping the field strip. You drop the brass weight through the chamber and barrel of your unloaded firearm and pull it through in your shooting direction. That's it.
What calibers does this .25-.27 FlexClean rope cover?
It's built for bores in the .25 to .27 caliber range, roughly 6.3 to 7.2mm. That covers common chamberings like 6.5mm, .257, .260, .264, 6.8mm, and .270. The caliber is engraved right on the brass weight so you can confirm you've got the right one.
Can I reuse the FlexClean bore cleaning rope?
Yes, it's designed to be washed and used again and again. The cord, sponges, and rubber balls are chemical resistant, so a rinse in warm water with a bit of dish soap gets it clean. Let it dry and it's ready for the next session.
Should I use it dry or with a cleaner?
You can run it dry, but it works best with Ballistol on the sponges. Put barrel cleaner on the front sponge and a bit of gun oil on the back so you clean and protect in one pull. Running it while the barrel is still warm helps lift residue too.
