FX Dynamic Express 600

FX Dynamic Express 600 is based on the FX Panthera platform, but features a larger air bottle, a different stock and a revised grip setup. The bottle has been upgraded from 300 cc to 480 cc to increase shot count and now connects directly to the action. The stock is built around this bottle, with a shoulder piece that can be adjusted vertically; compared with the Panthera, this setup increases the rifle’s length by 40 mm. The zero-angle grip has also been replaced with an angled AR-15-style grip. The rifle is available in 4.5 mm (.177), 5.5 mm (.22), 6.35 mm (.25), 7.62 mm (.30) and 9 mm (.35). Total air capacity is 636 cc, made up of the 480 cc bottle and a 156 cc Magnum XL plenum, with a 250 bar fill pressure and energy levels of up to 111, 123, 176 or 234 J depending on configuration.

The FX Dynamic Express 600 is engineered for maximum airflow and high performance, especially with slugs. Its single AMP MKII regulator has its own pressure gauge and can be adjusted precisely to reduce bottle pressure to the ideal plenum pressure for the chosen ammunition. The Dynamic Plenum Magnum XL provides 156 cc of regulated air around the barrel, ready for the next shot. Inside the Dynamic Block, an extra-large breech allows the use of slugs up to 13 mm long, while the newly developed one-piece High Power/Short Impulse valve delivers a large and extremely fast airflow. The Quick Tune system lets the shooter adjust hammer spring preload using a numbered macro wheel and a clearly scaled micro-adjustment. The Superior STX barrel system uses a changeable liner with rifling pressed in from the outside, helping keep the bore smooth and ensuring excellent sealing around the projectile. The rifle also features a refined adjustable match trigger with blade angle and height adjustment, a reversible short-throw side lever for ambidextrous operation, a full-length 17.75” Arca rail with M-LOK slots, a barricade block for repeatable positioning, and a 20 MOA Weaver/Picatinny scope rail for long-distance shooting. It weighs 3400 g, has a 600 mm barrel and an overall length of 1105 mm; no open sights or riflescope are included, while the package contains a case, fill probe and magazine.
