The BRASS JAGS DEWEY 30JM is an extra-long jag designed for .30 to .35 caliber firearms, enhancing patch contact with the bore for better fouling absorption.
It is compatible with Dewey Stainless, Rig, and Hoppe’s rods but requires adapters for Dewey Coated Rods, except for 17 and 20 caliber jags which fit coated rods without adapters.
Constructed from brass with male threading, the jag sizes are 5-40 for .17 and .20 caliber, and 8-32 male for calibers above .20, making it a universal tool for all calibers.
