Caliber bars provide the link between the weapon and the boresight optics. They display the bore axis of the weap-on barrel to be aligned. This way the ba-sic information for a highly accurate boresighting is obtained. The various caliber bars in the Airbus DS Optronics portfolio are specifically designed for particular calibers and weapon types to provide the utmost accuracy.

Small CaliberThe light weapon SKS caliber bars are designed to adjust the targeting optics of submachine guns, assault or sniper rifles and machine guns up to 14.5 mm caliber. No matter if the gun is carried, mounted or part of a weapon station or turret. A highly precise alignment with the boresight tools from Airbus DS Op-tronics can give the particular weapon a whole new combat value.

Medium CaliberRanging from 20 to 40 mm weapon cali-ber the SKS medium caliber bars cover all common machine cannon and auto-matic grenade launcher types in service. By enhancing the accuracy of the con-nected targeting devices the effect of cover-, support- or precision fire is maxi-mized. Thus equally minimizing the risk of collateral damage or friendly fire.

Large CaliberHeavy weapons from 57 to 155 mm cali-ber have the longest range and use the most effective but also expensive am-munition. To be of utmost effectiveness they have to rely on the highest possible aiming accuracy. The SKS caliber bars for heavy weapons from Airbus DS Op-tronics help to gain nothing less.
