The knurled portion of the Thompson Center Arms .50 Caliber Spin Extended Super Jag
spins freely to make loading sabots easier as the sabot is allowed to follow the rifling all the way down the bore until it is seated.
It also makes cleaning more efficient as the patch, swab, or bore brush follow the rifling grooves while the rod is pushed/pulled up and down the bore.
The concave tip allows use for loading.
Adds 3¾" to ramrod length.
The Extended Jag is necessary for cleaning the Encore 209 Magnum Muzzleloaders and Omega muzzleloaders.
