FX Panthera Hunter MKII Air Rifle
The FX Panthera MKII Hunter is a compact PCP air rifle built on the updated Panthera MKII platform. It combines controlled airflow, extensive tuning options and a practical layout for pellet and slug shooting. The forward-positioned air cylinder keeps the rifle short and well balanced for field use.
Compact and functional design
The 300 cc air carbon fiber air bottle is mounted underneath the barrel at the front of the rifle. This improves weight distribution and removes the need for a bottom rail. Two side-mounted Weaver/Picatinny rails allow accessory mounting, while the top rail features a 30 MOA incline for optics.
Quick Set Trigger (QST)
The adjustable trigger offers three preset profiles: PRS, hunting and benchrest. Switching between configurations can be done externally without disassembly, allowing quick adaptation to different shooting styles.
Regulator system
The AMP MKII regulator is fully adjustable and equipped with its own pressure gauge. It reduces pressure from the 250 bar bottle to a stable working pressure in the plenum, matched to the selected ammunition.
Dynamic plenum
The plenum surrounds the barrel and stores regulated air ready for each shot. Capacity depends on calibre:
50 cc for .22 (5.5 mm)
100 cc for .25 (6.35 mm) and .30 (7.62 mm)
Dynamic block and valve system
The enlarged breech accepts projectiles up to 13 mm in length. A high-flow, short-impulse one-piece valve ensures fast and consistent airflow. The raised airflow path improves cheek rest positioning and shooting ergonomics.
Quick Tune System
The hammer spring preload is adjustable via a macro wheel with indexed positions. Fine tuning is done with a micro adjuster. Settings can be reproduced accurately for consistent results.
Superior STX barrel system
The interchangeable STX liner features externally pressed rifling. This keeps the bore smooth and provides consistent sealing around the projectile.
