Lightweight and Durable
This electric airsoft gun is a Sportline product made of durable lightweight nylon polymer construction, which keeps the cost low, yet still high quality. This also allows you to run with this gun in the field without giving yourself too much fatigue as this electric airsoft SMG only weighs 1.6 KGs with its magazine. And since this is a sub-compact weapons platform, the airsoft MPX-K is easy to manoeuvre around tight corners
Customisable
The SIG AIR Proforce MPX-K has an M-Lok front handguard for all accessories, a top Picatinny rail, a side folding minimalist stock and a picatinny rear-end rail that allows for the mounting of compatible stocks. The stocks are interchangeable with the SIG AIR Proforce MCX airsoft gun and SIG AIR Proforce airsoft MPX, just like in the real steel world! 
Version 2 Gearbox
The SIG AIR Proforce MPX-K Sportline packs a modified Version 2 gearbox which features a quick change spring system to allow for switching out lighter or heavier springs, as well as full compatibility with most standard version 2 gearbox components like the piston assembly and rotary gears.
Battery
The battery is wired to the front of the gun and it will take 7.4V – 9.6V batteries, please note that this gun will not take 11.1V batteries.
Adjustable Hop-up
It features an enhanced hop up, which can be accessed by pulling back the charging handle just like most M4 / AR-15 style electric airsoft rifles and turning the adjustment dial in where the chamber would be located. 
Ambidextrous Control System
The fire controls and magazine release are ambidextrous which makes it very easy to manipulate shots and reloads both on the strong and weak hand. 
Advanced Gas Piston System
One of the standout features of the Sig Sauer MPX-K Sportsline is its short-stroke gas piston system. This system significantly reduces recoil and improves reliability, making the firearm suitable for sustained use in rigorous conditions. The gas piston operation also minimizes fouling, ensuring the weapon remains clean and functional even after extended use.
