Gamo GX-40 PCP 4.5mm Air Rifle

The Gamo GX-40 PCP 4.5mm Air Rifle is a compact and accurate air rifle which features a last generation precharged pneumatic air system (PCP). Gamo’s last generation PCP system provides a smooth, powerful and accurate shooting due to its sophisticated compression system.

This state of the art technology consists on a strengthened steel air cylinder which is able to deliver high power levels by using a mechanic opening valve. This outstanding airgun is composed of a precise and reliable cold hammer forged barrel and a brand new ergonomic and adjustable polymer stock, which guarantees a perfect sight to target alignment.

PCP cylinders can be charged in a few minutes using a pump, so they become a really good alternative to classic break barrel carbines. Even though their autonomy is limited to the remaining air quantity available in the tank, they offer a really accurate recoil-free shooting experience which break barrel airguns are still far from achieving.
