Airsoft Starter Set – King Arms x SIG SAUER MPX-K Sportline SMG + Accessories

MPX-K Sportline – compact setup for dynamic CQB

This set is designed for players looking for a lightweight and compact airsoft replica for fast-paced gameplay, especially in CQB and at shorter ranges. At its core is the licensed King Arms x SIG SAUER MPX-K Sportline airsoft SMG, complemented by a Li-Po battery, charger, additional magazine, 0.25 g BBs and a red dot sight. This gives you a coherent setup from the start without having to source the basic equipment separately.

The core of the set – King Arms x SIG SAUER MPX-K Sportline airsoft SMG

The MPX-K Sportline is a licensed SIG SAUER airsoft replica developed by King Arms with fast and dynamic gameplay in mind. This compact airsoft SMG measures approximately 390–590 mm and weighs around 1525 g, making it well suited to indoor arenas, buildings and other confined spaces.

The lightweight body is made mainly from nylon polymer, while metal is used in the more heavily stressed parts of the construction. The side-folding stock further reduces the replica's overall size, while the ambidextrous fire selector and magazine release make operation comfortable for both right- and left-handed users.

Technical features of the MPX-K Sportline

At the heart of the replica is a modified V2 gearbox with a metal shell and steel gears. The design features a quick spring change system, making it easier to adjust the replica's performance to the limits required by a particular airsoft field.

Key technical features:

• modified V2 gearbox with a metal shell
• steel gears and a quick spring change system
• rotary Hop-Up chamber for adjusting the BB flight path
• inner barrel approximately 140 mm long
• muzzle velocity of approximately 300 FPS
• semi-automatic and full-auto fire modes
• front wiring with a small Tamiya connector

M-LOK, Picatinny and 14 mm CCW thread

The MPX-K Sportline offers plenty of room for external configuration. The M-LOK handguard allows compatible accessories to be fitted, while the long upper Picatinny rail provides a convenient mounting base for the red dot sight included in this set.

The 14 mm CCW thread allows you to add a compatible tracer unit, mock suppressor or other muzzle device later on. The replica also comes with folding flip-up iron sights.

Power supply – 7.4 V Li-Po and Specna Arms EASY charger

The set includes a 7.4 V 1200 mAh 20C/40C Li-Po battery with a Tamiya connector and a Specna Arms EASY charger. Li-Po batteries combine compact dimensions with good current output and are a popular choice for electric airsoft replicas.

The Specna Arms EASY charger supports 2S 7.4 V and 3S 11.1 V Li-Po batteries and features balanced charging. Three indicator LEDs show the charger's operating status and charging progress.

Two 100-round mid-cap magazines

The standard MPX-K package includes a 100-round mid-cap magazine. This set adds a second compatible King Arms x SIG SAUER magazine with the same capacity.

In total, you get two magazines with a combined capacity of 200 BBs. Mid-cap magazines do not require winding and do not produce the characteristic rattle of loose BBs, which suits the fast-paced nature of the MPX-K.

Specna Arms CORE TRX red dot sight

The compact Specna Arms CORE TRX complements the setup for fast, short-range gameplay. The sight can display either a red or green aiming dot, with 7 brightness levels available for each colour.

• 2 MOA aiming point
• 1x magnification
• windage and elevation adjustment
• 7 brightness levels for both red and green dots
• low and high mounts included
• powered by a CR2032 battery

Specna Arms CORE 0.25 g BBs – 3000 pcs

A supply of 3000 Specna Arms CORE 0.25 g BBs lets you prepare your magazines and get started with training or your first games straight away. The 0.25 g weight is a versatile choice for standard AEG replicas and works well with the performance level of the MPX-K Sportline.
