Changing Calibers- The Blaser R8 Standard Barrel makes everything possible
Like the Blaser R93, the Blaser R8 is a modular system capable of switching barrels. When changing from one caliber to another within the same caliber family, no bolt head change is necessary. If going outside of the caliber group during a barrel exchange, the bolt head has to be changed as well. However, the bolt head can be exchanged quickly and easily.
Changing barrel contour
Every Blaser R8 receiver will accommodate all barrel contours. However, for an appropriate fit, the proper forearm is also required. Everything starts with the Blaser R8 Standard barrel; all R8 barrel channels will initially accept any standard weight barrel. Please note: larger barrel contour (Semi-Weight or Match barrels) will not fit in a standard professional stock or wooden forearm, options are available from Blaser to accommodate these barrel options.
NOTE: Except for the Blaser Saddle Mount, no R8 components are interchangeable with R93 components.
