Blaser R8 locking chamber right DLC optics

Locking chamber with "Diamond Like Carbon" coating for Blaser R8 straight pull repeater. The black glossy bolt head is DLC-coated and thus has an extremely resistant, durable, and hard surface. This is about 8 times harder than the hardest steel.
The chamber head can be exchanged depending on the respective caliber group, i.e., the caliber used. Blaser distinguishes between different caliber groups: KK, Mini, Standard, Medium, and Magnum.
So, for example, if you switch from a standard caliber to a medium or magnum caliber, you only need to change the chamber head on the Blaser R8 and not the entire bolt.
