About the FX Royale 400
The FX Royale 400 is a regulated pre-charged pneumatic (PCP) air rifle produced by FX Airguns of Sweden. It features a 400cc carbon-fibre air cylinder, a reversible side-lever cocking action, a 12-shot removable rotary magazine (16 shots in .177), and the FX Smooth Twist shrouded and moderated match barrel for a quiet report. A fully adjustable two-stage match trigger and a three-step power adjuster on the left side of the breech let shooters tune the rifle, which in .22 calibre produces around 30 ft-lbs of muzzle energy. It was a flagship sporter-stocked hunting and target rifle before being superseded by the FX Crown.
FX Airguns was founded by Swedish airgun designer Fredrik Axelsson, and the Royale represented the firm's high-end sporter PCP before its later modular platforms such as the Crown and Impact took over the top of the range.
