Bleiker is a Swiss manufacturer of bolt-action rifles aimed solely for use in ISSF and CISM target shooting.

At the 2014 ISSF World Shooting Championships, Bleiker Challenger actions were used to win 10 individual medals in the 50metre Prone and Three Position Rifle events.

When properly set up, some users are able to load without raising their elbow off the ground, which over the course of an ISSF Prone match offers a competitive advantage when trying to maintain a consistent position compared with actions using longer bolts that require more movement to reload.

Bleiker provide complete rifles, as well as selling their action for gunsmiths to integrate into custom builds.
