Every Blaser rifle or combination gun can be fitted with an original Blaser Saddle Mount. After being zeroed in once, the rifle scope can be removed and replaced in just three steps, with no need for tools, as often as desired, with 100% return to zero. This allows you the flexibility to use different scopes on the same barrel. Four inconspicuous notches on the chamber end of the barrel take the onepiece mount without tension. The barrel itself is totally free to oscillate. No further work is required on the firearm, and there is no need for large mount bases that can interfere with your sight picture or the look of the rifle.
