Tactical Agility: The Sig Sauer MPX Gen 2 Air Rifle

The Sig Sauer MPX Gen 2 is a high-performance 4.5mm (.177) caliber air rifle that brings the legendary ergonomics and rapid-fire capability of the MPX platform to the world of airguns.

This “Generation 2” update takes everything that made the original MPX a best-seller and refines it with modern tactical features, including a flat blade trigger and an M-LOK handguard.

Finished in a striking Flat Dark Earth (Tan), this rifle is a 1:1 scale replica of the firearm used by elite units globally, now available for enthusiasts at Huntsman Sports.

Compact Gen 2 Upgrades for 2026

The Sig Sauer MPX Gen 2 is designed for shooters who prioritize speed and maneuverability. Unlike the longer MCX, the MPX features a shorter 8-inch rifled steel barrel, making it ideal for clearing “rooms” in tactical training or quick-transition target practice.

• Flat Blade Trigger: The Gen 2 features a redesigned flat trigger blade. This provides a more consistent, linear pull, which is essential for maintaining accuracy during the semi-automatic rapid fire this rifle is known for.
• M-LOK Handguard: The aluminum handguard has been updated to the M-LOK standard. This allows you to mount tactical accessories directly to the rail
• Improved Ergonomics: A reduced-angle pistol grip and a low-profile recoil pad on the redesigned buttstock ensure the rifle feels more natural in the hand, reducing fatigue during long plinking sessions.

30 Rounds of Semi-Auto Power

The heart of the Sig Sauer MPX Gen 2 is its patented 30-round RPM (Rapid Pellet Magazine). This belt-fed system is remarkably reliable, allowing you to fire all 30 pellets as fast as you can pull the trigger.

• Power Source: The rifle is powered by an 88g CO2 cylinder which is housed inside the quick-release buttstock. This provides enough air for multiple magazine cycles before needing a swap.
• Rifled Barrel Precision: Despite its compact size, the 8-inch barrel is precision-rifled. This ensures that every .177 pellet maintains a stable flight path, making it effective for target shooting at ranges up to 15–20 meters.

Authentic Build Quality

Because this is an official Sig Sauer product, the Sig Sauer MPX Gen 2 is built to the same exacting standards as their firearms. It features a full metal receiver and high-quality synthetic furniture, giving it a realistic weight of 6.2 lbs. The Tan finish is professionally applied to match the real-world FDE (Flat Dark Earth) coating used on military-contract rifles
