FX Dynamic Express, 600

The FX Dynamic Express 600 is a regulated PCP air rifle in .177 (4.5 mm) in the Express configuration of the first-generation FX Dynamic. The air is held in a 480 cc carbon fibre bottle built into the rear of the stock under a moulded tank cover, and the rifle is filled to 250 bar. With a 600 mm barrel it is 1107 mm long and weighs approx. 3400 g. It is loaded with a reversible sidelever from a 21-shot magazine.

The Dynamic is FX's platform for high energy and heavy projectiles, and the Express version brings it all together in a compact, balanced package with no bottle under the front of the barrel. Above the barrel sits a 156 cc Magnum XL power plenum, which together with the balanced valve gives enough air for slugs. The fore-end has an Arca rail with M-LOK, so a bipod mounts directly.

Bottle in the stock, 156 cc plenum and Quick Tune

Five features that define the Dynamic Express:

• 480 cc carbon fibre bottle in the stock: The bottle is removable and sits at the rear, where it does not interfere with the fore-end or the balance, and the 250 bar fill pressure gives many shots per fill.
• Magnum XL plenum and Dynamic valve: The large plenum above the barrel and the short, balanced valve deliver a strong, consistent air pulse – for shooting heavy slugs at long range.
• Quick Tune System: The hammer spring adjusts in small and large steps, so the energy can quickly be matched to the ammunition – from light diabolo pellets to slugs.
• AMP MKII regulator with two gauges: The regulator can be adjusted from the outside, and two Wika pressure gauges show both bottle pressure and regulator pressure.
• Reversible sidelever and wide magazine: The cocking lever can be moved to the left side, the magazine takes projectiles up to 13 mm long, and an AR grip, Picatinny rail and Foster quick-connect fill fitting are included.

Maintenance and safety

• Only fill with clean, dry compressed air via the Foster fitting, and do not exceed 250 bar.
• Check the O-rings at the bottle, fill port and magazine regularly, and replace them when worn.
• Release the air from the system before unscrewing the bottle, so threads and seals are not put under load.
• Store the rifle unloaded and out of reach of children. Check the air rifle regulations in your country before purchase – rules on power and age limits differ across the EU.
