Centra Spacer Block Club – spacers 5 mm / 8 mm / 20 mm

Spacers for Centra Block Club used to adjust the height of the rear sight. Available in three sizes: 5 mm, 8 mm and 20 mm.

Product description

Centra Spacer Block Club spacers are designed to adjust the height of the rear sight when using the Centra Block Club mounting system on biathlon rifles and other precision rifles.

By adding spacers, the shooter can fine-tune the sight height to match shooting position, stock configuration and individual ergonomics. A correct sight line helps achieve a more natural shooting position and improved control during the shot.

The spacers are installed between the rifle and the Centra Block Club mount and are available in three different heights to provide flexibility when setting up the rifle.

When stacking multiple spacers on top of each other, it is recommended to use a light thread-locking compound on the screws to ensure the assembly remains secure during shooting and transport.

These spacers are ideal for shooters who want to fine-tune their rifle setup and achieve the optimal sight height.

Correct sight height is an important part of achieving a stable and repeatable shooting position in biathlon. By adjusting the height of the rear sight, the shooter can align the natural head position with the rifle’s sight line, which helps maintain a relaxed neck position and consistent eye alignment with the diopter.

The Centra Block Club spacer system allows shooters to fine-tune their setup by adding spacers between the rifle and the rear sight mount. This makes it easy to adapt the rifle to different shooting positions, stock configurations and personal ergonomics.

Small adjustments in sight height can make a noticeable difference in shooting comfort and stability, especially in prone shooting where head position and cheek pressure must remain consistent.

Centra spacers are precision manufactured and designed to work perfectly with the Centra Block Club mounting system. The available heights (5 mm, 8 mm and 20 mm) allow shooters to build the exact sight height needed for their individual setup.

When multiple spacers are stacked together, applying a light thread-locking compound to the screws can help ensure that the mount remains secure during shooting and transport.
