The FX Panthera is unlike any previous FX Airguns rifle. It is a dedicated slug rifle, purpose-built for precision competition.
The Panthera includes technology displaying a generational leap-forward for an airgun. It begins with the new Dynamic Block. A new breech block designed from the ground up for performance slug shooting. The Dynamic Block utilizes a compact one-piece valve. This High-Power / Short-Impulse Valve allows an immense and precise flow of air.
The plenum design (i.e. Dynamic Plenum) feeding the Panthera is revolutionary and the first of its kind. It is an over-the-barrel plenum. It provides a consistent regulated pressurized plenum around the barrel. It adds increased rigidity to the barrel. Allows many plenum lengths employed to match the caliber and power of the rifle. The single AMP MKII Regulator maintains precise levels of pressure. Three Plenum sizes at first: a Micro Plenum (sub 12ft/lb rifles), Macro Plenum (62cc) & Magnum XL Plenum (156cc).
The results of the Dynamic Breech & Plenum are extraordinary! Constant 10 shot strings with standard deviations in the low 1.0–2.0 range and extreme spreads as low as 3-4. Ability to control air flow paired with the FX Superior STX barrel using premium slugs. Competition wins, and not in only airgun competitions! .22LR shooters will identify the ability to shoot the same BC slugs and weights. With the control and standard deviations that only FX Airguns can deliver.
The Panthera stock is for competition. It features a 14.75” long Arca rail complete with M-LOK sections. A barricade block nestled next to the breech. You can achieve an ideal balance point by adding external M-LOK compatible weights. Or internal FX Barrel Weights that attach under the shroud. An adjustable buttstock and an adjustable cheekpiece that are ambidextrous. The Panthera’s air source is a 300cc carbon fiber bottle attached in the rear. Filled via a rear located foster quick disconnect.
The Dynamic Block has a larger breech than previous air rifles. Allows projectiles up to 13mm in length. It uses the Standard Side-Shot Magazine with a deeper lid to load longer length slugs. The FX Panthera employs the Quick Tune System. It is the same as found on the FX Impact M3. A 20MOA picatinny scope rail. A zero-angle AR grip. An ambidextrous sidelever cocking handle that is reversible to the left side. Dual angled Nanometers on the left side of the block. These Nanometers show the bottle pressure and the regulated plenum pressure.
Three configurations: Panthera 700, Panthera 600 & Panthera 500 (corresponding to barrel length). The Panthera 700 & 600 use the FX Superior Heavy STX barrel liner as standard for slug shooting. The Panthera 500 uses FX Superior STX barrel liner for pellets and light-weight slugs. The rifle allows for the quick change of barrel liners. Changing calibers and barrel lengths only done by an authorized FX dealer. Accessories: a bag rider. Barrel weights. Offset M-LOK weights. Smaller profile competition Mini-Mag, Picatinny accessory sections, and an optional tungsten hammer.
The new FX Panthera will forever change the precision rifle world. It feels and shoots like a precision 22LR. Straight-back recoil. Laser sharp precision and accuracy only found with an FX Airgun!
