About the Diana 54 Airking
The Diana 54 Airking is a full-power, single-shot, spring-piston air rifle chambered in .177 (4.5mm) pellets. Its defining feature is a recoilless 'floating action' system in which the entire barrel-and-cylinder assembly rides on internal rails and slides rearward against the spring's recoil impulse, cancelling out felt kick and preserving accuracy. Cocked by a right-side sidelever and fitted with an adjustable two-stage T06 trigger, it is a favourite of field-target and precision springer shooters.
Diana, founded as Mayer & Grammelspacher in Rastatt, Germany in 1890, is among the oldest airgun makers in the world and takes its name and emblem from the Roman goddess of the hunt. The Model 54 built on the recoilless sliding-rail principle Diana pioneered with the Model 52/48 series, giving spring-piston shooters near-recoilless accuracy without the cost of a PCP system.
