The new Blaser B75 “Bergstutzen” (over & under double rifle featuring two different calibers) was introduced based on the earlier BBF ES 70.

Barrel selector on the B75
Apart from the barrel selector which allows the top barrel to be selected when using the set trigger, the B75 system is identical to the ES 700. This allows a combination barrel to be inserted. Thus introducing the modular system.
The top rifle barrel is inserted in a carrying tube which can be regulated at the muzzle. This renderss the complex soldering of the barrels required for regulating unnecessary.
    
A new scope mount is introduced:
The Blaser pivot mount (BSM) became the most popular mount in German speaking countries due to its precision and simple handling.

The Blaser Pivot Mount
Almost all Blaser rifles were fitted with the BSM, with some other rifle manufacturers also using it. Later came a further development, the Blaser bridge pivot mount (BBSM). This mount served for 20 years in the industry (until 1995) – when the Blaser scope mount for all Blaser models was released. The era of the pivot mount then came to an end, although individual pieces are still produced today.
