Warning for FX Airguns Owners
Recently, a trend has emerged in the Czech Republic involving the tuning of FX Airguns airguns to achieve maximum power without the necessary knowledge or adjustments. We would like to alert all owners of these weapons to the potential consequences of such modifications.

FX Airguns Design and Performance
All standard versions of FX Airguns airguns are designed to provide optimal performance relative to air consumption. If you aim to achieve the maximum performance stated by the manufacturer, it is crucial to understand that this is not possible with the stock version without additional modifications. The manufacturer emphasizes on its website that specific adjustments are required to reach maximum performance levels.

The Need for a Heavier Hammer Weight
To ensure proper valve opening at higher regulator pressures, installing a heavier hammer weight is necessary. Without it, the airgun will not function optimally, and there is a risk of damaging the weapon.
Examples:
FX Panthera Dynamic King DRS: Requires an 8mm hammer weight weighing 13.2 grams. The manufacturer advises against using tungsten hammer weights for this model.
FX Impact: Requires a tungsten hammer weight weighing 25.4 grams.
These additional weights are available in the Czech Republic for approximately 500 to 800 CZK (approximately €20.41–32.65, $22.22–35.56, or £17.54–28.07).

Using the Correct Ammunition
Another common mistake is using lightweight pellets (diabolo) due to their lower cost. To achieve the advertised performance, heavy ammunition is essential, as the performance is determined by the mass of the projectile relative to its velocity.
Key Points:
Pellets are not designed for high-velocity shooting. For this purpose, slugs—shaped like bullets from firearms—are used. Slugs offer superior ballistic properties, greater stability in flight, and reduced velocity loss, enhancing accuracy over longer distances.

Dynamic Valve in FX Panthera Dynamic King and DRS
These models are equipped with a dynamic valve that requires backpressure in the barrel, determined by the weight of the projectile, for proper operation. Lightweight projectiles do not allow this system to function correctly.

Final Recommendations
Modifications to airguns should only be carried out with sufficient knowledge or entrusted to professionals. Incorrect adjustments can result in weapon damage and jeopardize your safety.
Note: This warning is not an official statement from FX Airguns but serves as advice for users.
