Blaser R8 .243 Winchester Semi-Weight barrel with sights.
The Blaser R8 is a modular system that can switch barrels. When changing from one caliber to another within the same caliber family, no bolt head change is necessary. If changing outside the caliber group during a barrel exchange, the bolt head must be changed, but it can be exchanged quickly and easily.
Note: Except for the Blaser Saddle Mount, no R8 components are interchangeable with R93 components.
