Brass Barrel shims X 2.

Weirhauch barrel shims made of Copper so as to prevent seizing of the shims and breech jaws and marking the inside of the breech jaws.

Could possibly be doubled for better bearing surface and better lubrication. Use with Moly MS2 Lube.

There is an option to add more shims under the add tab.

Large centre hole so they can be used on most break barrel guns.

Adjust barrel jaws to remove any side play, but do not over tighten
