The FX King Synthetic 500mm PCP Air Rifle puts the King's Panthera-derived block and over-the-barrel plenum into a black soft-touch synthetic stock. You get the same action, regulator and barrel as the GRS laminate King, in a stock built to shrug off wet days in the field.
An AMP MKII regulator feeds a 62cc macro plenum for a flat, consistent shot string. Dual angled Wika gauges show bottle and regulator pressure while the rifle sits in your shoulder. The Quick Tune System adjusts hammer spring tension without tools, and the 500mm Superior STX liner barrel handles pellets and slugs. A 480cc carbon bottle gives up to 285 shots per fill in .177. The rifle ships in an FX hard case with cut foam. Air rifles at or under 12 ft/lbs need no licence in England and Wales; buyers must be over 18.
