Clenzoil Cobra Bore Cleaning System 44/45 Cal

Sized for 44 and 45 caliber bores, the Clenzoil Cobra replaces a cleaning rod with a flexible pull through. Drop the weighted end in at the chamber, pull it out the muzzle, and the integrated bronze brush scrubs while the woven cotton braid behind it wipes the loosened fouling out of the barrel. One pass does what several rod strokes and a handful of patches used to.

That makes it a good fit for revolvers and 45 caliber handguns that get cleaned at the range rather than on a bench. The braid washes out in soapy water and goes back in the bag, so this is not a consumable. Clenzoil suggests pairing it with their Field & Range solution, but it works with any bore solvent.
