Air rifle Sig Sauer MPX II 4.5 mm offers shooters the opportunity to train with a replica of the famous tactical carbine MPX in the comfort of the shooting range or the garden. It retains the realistic appearance, ergonomics and controls of the live-fire version, but shoots lead pellets. Thanks to CO₂ propulsion it offers rapid shooting in semi-automatic mode and is ideal for dynamic training, manipulation drills and fun target shooting.
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 intended for shooting pellets, which provides better projectile stability and consistent hits on target. Included is a high-capacity 30-shot magazine, which allows for longer shooting strings without constant reloading and underlines its dynamic character.

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 placement is designed so that it does not affect the ergonomics or the balance of the gun. The advantage of the 88 g cartridge is a long service life per filling, so the user can fire a large number of shots without frequent replacement. CO2 power ensures consistent performance in semi-auto mode and a smooth cycle of the gun for fast shooting.
The trigger mechanism is designed to reproduce the feel of the live-fire MPX trigger as faithfully as possible. The shape of the trigger, its position and travel contribute to very realistic manipulation training. The user thus gains similar ergonomics and trigger finger work as with the live-fire tactical carbine. To increase safety, the gun is equipped with a lever safety, which allows fast and intuitive setting to safe or fire without changing the grip.
The MPX II is fitted with folding flip-up sights, which enable 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 attach your favourite accessories. The handguard integrates an M-LOK mounting system, allowing additional tactical accessories to be added – e.g. a flashlight, laser or vertical foregrip. The MPX II thus offers wide possibilities for individualisation and adaptation to your shooting style.
