The FX Panthera MK2 .30 CAL 600mm variant balances compact maneuverability and high-velocity slug-pushing performance. Built on the upgraded Dynamic Block platform, this mid-length configuration features a tightened barrel-to-action interface and an over-the-barrel plenum system to maximize shot-to-shot consistency without the front-heavy feel of the larger 700mm builds. 
Core Technical Specifications
The standard factory layout for the 600mm platform delivers standard precision metrics across multiple calibers:
  • Barrel Length: 600mm standard length.
  • Plenum Volume: 156cc to 163cc over-the-barrel Dynamic Plenum.
  • Air Capacity: 300cc rear-mounted carbon fiber bottle.
  • Maximum Fill Pressure: 250 BAR (3,625 PSI).
  • Regulator System: Externally adjustable AMP MKII regulator (operating up to 170 BAR).
  • Optics Mounting: Integrated 30 MOA Picatinny top rail.
  • Chassis Rail: Monolithic lower Arca-Swiss and M-LOK rail featuring built-in barricade stops.
  • Muzzle Thread: Standard 1/2" UNF for moderators.
  • Total Weight: ~8.8 lbs (~4.0 kg) un-scoped. 
Key Upgrades on the MK2 Platform
  • Quick Set Trigger: The legacy trigger is replaced with a 3-in-1 adjustable system first showcased on the FX Impact M4, allowing match, hunter, or tactical configurations. 
  • Rigid Monolithic Rail: Features an updated, extended one-piece chassis rail with built-in slots for internal weights and threaded points to fix balancing weights. 
  • Enhanced Breech Tolerance: Designed with tighter block-to-barrel machining tolerances to completely eliminate point-of-impact (POI) shifts due to weather or harsh handling. 
  • Higher Ergonomics: Includes a redesigned rear assembly that offsets the cheekpiece upward for clearer scope sightlines and offers built-in QD sling attachment points. 
Available 600mm Configurations & Calibers

  • .177 Caliber: Built primarily with standard Smooth Twist X (STX) Superior liners.
  • .22 Caliber: Ships with Superior Heavy STX liners Optimized for precision slugs.
  • .25 Caliber: Utilizes the Superior Heavy STX system to bridge long-range pellet and hunting slug uses.
  • .30 Caliber: Engineered with increased port geometry for high foot-pound energy transfer. 
Tuning and Upgradability
Because the Panthera MK2 .30 cal platform shares architecture with the Dynamic and BenchMark platforms, the 600mm platform remains fully modular. Shooters looking for ultimate rigidity can swap the standard assembly for the 20mm heavy solid-steel Bull Barrel kit, which threads directly into the Dynamic Block for optimal harmonics. Converting between calibers or extending to a 700mm setup requires modular FX barrel housing sleeves, a matching length shroud, a caliber-specific probe, and brass transfer ports.
