The BRASS JAGS DEWEY 40JM is designed to effectively clean .40, .41 caliber and 10mm firearms, with raised segments for improved fouling absorption.
Compatible with Dewey Stainless, Rig, and Hoppeās rods, but requires adapters for use with Dewey Coated Rods, except for 17 and 20 caliber male threaded jags.
Constructed from brass with male threading; the jags come in different sizes, including 5-40 for .17 and .20 caliber, and 8-32 male for calibers above .20.
