Blaser a0811113 R8 Selous Semi Weight Barrel 300 Win Mag

Changing Calibers

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. R8 barrels does not come with the correct magazine insert.

Changing barrel contour

Every Blaser R8 receiver will accommodate all barrel contours. However, for an appropriate fit, the proper forearm is also required. Using a forearm for a larger contour is not a problem if the user does not mind the extra gap between the barrel and forearm. A larger barrel contour will not fit in a standard professional or wooden forearm though. Extra forearms are available for wooden guns but not the professional since it is a one piece composite stock.
