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

Air rifle Sig Sauer MPX II 4.5 mm 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 fires lead pellets. Thanks to CO₂ propulsion it offers rapid fire in semi-automatic mode and is ideal for dynamic training, handling practice and fun target shooting.

Robust construction and practical parameters

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

Internal system and 88 g CO2 power

The operation of the gun 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 location is designed so that it does not disrupt the ergonomics or balance of the gun. The advantage of the 88 g cartridge is the long runtime per fill, so the user can fire a large number of shots without frequent replacement. CO2 propulsion provides consistent performance in semi-auto mode and a smooth cycle of the gun for fast shooting.

Trigger like on the live-fire MPX and confident handling

The trigger mechanism is designed to replicate the feel of the live-fire MPX trigger as faithfully as possible. The shape of the trigger, its placement and travel all contribute to very realistic handling training. The user thus gets similar ergonomics and finger placement as with the live-fire tactical carbine. To increase safety, the gun is equipped with a lever safety, which allows quick and intuitive engagement and disengagement of the safety without changing the grip.

Aiming, flip-up sights and mounting system

The MPX II comes with folding flip-up sights, which allow instant aiming right out of the box. However, if you prefer an optic or red dot sight, you will appreciate the 22 mm mounting rail on the top of the gun, where you can easily mount your favourite accessories. The forend features an integrated M-LOK mounting system, thanks to which additional tactical accessories can be added – e.g. a torch, laser or vertical foregrip. The MPX II thus offers wide possibilities for individualisation and adaptation to your shooting style.
