FX PANTHERA MKII 700 5.5MM
The FX evolution continues with the highly anticipated FX Panthera MKII 700 5.5mm. This MKII version redefines what the Dynamic Block platform can achieve. Delivering improved rigidity and refined ergonomics, as well as next-level precision. All while maintaining both the power and versatility shooters trust.
When FX introduced the Panthera and Dynamic in 2022, the goal was clear… Build a rigid, competition ready air rifle platform capable of extreme power and precision, as well as tunability. Without the complexity of modular systems, of course. That platform became what shooters now call the Dynamic Block. Fast forward to today, and the Dynamic Block has done something few designs achieve. It has earned relevance across disciplines – PRS, Hunting and now benchrest. Both the Panthera MKII and Dynamic MKII represent the next step in that evolution. Same proven block. Same raw performance potential of up to 100 ft/lbs. Now refined, reinforced and also modernized based on real-world shooter feedback.
A More Rigid Foundation
At the heart of the MKII update is an all-new solid front stock design that grips the Dynamic Block at multiple anchor points. The result is a noticeably stiffer, more unified system eliminating flex and increasing repeatability under recoil. The scope rail is extended and now integrated into the front stock, delivering increased rigidity with 30 MOA built-in incline. The new rail also improves better alignment between barrel, block and optic with incorporated alignment pins. Panthera MKII’s new stock includes a full-length ARCA rail underneath, paired with M-LOK slots along the sides, as well as a QD sling mount. Furthermore, they added a new barricade stops design and on the inside of the rail they incorporated slots to add internal weights.
One Precision Mechanism. 3 Personalities.
First introduced on the FX Impact M4, the Quick Set Trigger has quickly become one of the most appreciated advancements in the FX line-up. Now, it is fully integrated into the Panthera MKII and Dynamic MKII platform. This is not just an adjustable trigger. It is a 3-in-1 configurable trigger system, designed to adapt to your discipline.
Improved Tolerances
With the MKII evolution of the Dynamic Block platform, they have further refined the barrel interface by tightening critical tolerances and upgrading key materials within the mounting system. The result is a stronger, more secure barrel-to-action connection designed for improved consistency and long-term durability.
Improved Ergonomics
By raising the airflow passage higher at the rear of the block they created more room around the grip, while at the same time raising the cheekrest for a better sight picture. Combined with the adjustable recoil pad, they achieved an overall more comfortable and ergonomic shooting experience.
Features
Featuring a redesigned forend with improved weight channels, expanded ARCA and M‑LOK integration, and a built‑in 30 MOA Picatinny optics rail.
Refined internal power system with a higher‑flow valve, quicker pressure recovery and an enlarged plenum that pairs seamlessly with the AMP MKII regulator.
The 163 cc plenum now surrounds the barrel, paired with an enlarged breech for longer slugs and a high‑flow, short‑impulse one‑piece valve.
More responsive Quick Set Trigger offering three selectable profiles for PRS, hunting, and benchrest. Also provides a wider tuning window through macro/micro hammer adjustments, giving shooters precise command over power and feel.
Stiffer, better balanced, and more adaptable chassis, resulting in smoother impulse control and more authority when driving heavy slugs.
A reinforced aluminum forend boosts rigidity, adds a full Arca rail, M‑LOK slots, internal weight channels, and an integrated 30 MOA Picatinny rail.
Rear airflow routing is raised for better cheek weld.
The Superior STX barrel system continues with interchangeable liners and smooth, externally pressed rifling.
