The Highlander Rifle uses the Bergara Premier Action which is designed as a two-lug system that features a separate floating bolt head to ensure contact with the lug abutments in the action. It also features a cone-shaped bolt nose for smooth feeding of the cartridge, and a spring-loaded sliding plate extractor located in the front of the lower locking lug. The one-piece bolt body is stainless steel with a pad at the rear to accept the threaded-in bolt handle.
