PRODUCT DESCRIPTION

Air rifle Sig Sauer MPX II 4.5 mm – a tactical legend in a CO2 version

Sig Sauer MPX II 4.5 mm air rifle gives shooters the opportunity to train with a replica of the famous tactical carbine MPX in the comfort of the shooting range or garden. It retains the realistic appearance, ergonomics and controls of the live-fire version, but shoots lead pellets. Thanks to its CO₂ power source it offers fast shooting in semi-automatic mode and is ideal for dynamic training, manipulation drills and fun sport shooting.

Robust construction and practical parameters

The MPX II is designed as a tactical carbine with a durable polymer stock and handguard, which reduce weight and increase resistance to damage. It uses a rifled barrel designed for shooting pellets, providing better projectile stability and consistent hits on target. It comes with a high-capacity 30-round magazine, allowing for longer shooting strings without constant reloading and underlining its dynamic character.

Internal system and 88 g CO2 power

The operation of the rifle is handled by a CO2 system using a large 88 g cartridge, which is installed in the body of the rifle – in the stock section. The cartridge placement is designed so that it does not interfere with ergonomics or the balance of the rifle. The advantage of the 88 g cartridge is the long endurance per fill, allowing the user to fire a large number of shots without frequent replacement. The CO2 drive provides consistent performance in semi-auto mode and a smooth cycling of the rifle for rapid fire.

Trigger like the live-fire MPX and confident handling

The trigger mechanism is designed to replicate the feel of the live-fire MPX trigger as closely as possible. The shape of the trigger, its position and travel contribute to highly realistic manipulation training. The user thus gains similar ergonomics and trigger finger work as with the live-fire tactical carbine. To enhance safety, the rifle is equipped with a lever safety, which allows quick and intuitive engaging and disengaging of the safety without changing the grip.

Aiming, flip-up sights and mounting system

The MPX II comes fitted with folding flip-up sights, enabling immediate aiming right out of the box. If you prefer an optic or red dot sight, you will appreciate the 22 mm mounting rail on the top of the rifle, where you can easily attach your favourite accessories. The handguard integrates an M-LOK mounting system, allowing the addition of further tactical accessories – e.g. flashlight, laser or vertical foregrip. The MPX II therefore offers extensive options for individualisation and adaptation to your shooting style.
