The Blaser R8 HO (Hornet) Right Hand Bolt Head is the factory-specific bolt head designed exclusively for use with the .22 Hornet caliber on the Blaser R8 modular rifle system. The R8's renowned interchangeable barrel platform allows shooters to swap calibers quickly, and when crossing caliber groups, a corresponding bolt head change is required — and the HO designation is unique to the .22 Hornet, making it a rare and specialized component within the R8 accessory lineup. Sized specifically for the Hornet's diminutive cartridge head, this right-hand bolt head installs in minutes and transforms the R8 into a capable small game, varmint, or range trainer chambered in the classic .22 Hornet. Whether you're building a dedicated small-caliber setup or adding versatility to an existing R8, this bolt head is the essential piece that makes it possible.
