King Arms x Sig Sauer MPX-K Sportline airsoft submachine gun
Airsoft submachine gun created as a result of cooperation between King Arms and Sig Sauer.
The model is made almost entirely of durable polymer - only the most sensitive parts, such as the QD mount or screws and pins, are made of metal.
The model has an M-LOK handguard and a dorsal RIS rail, which allows the attachment of e.g. red dot sights. A mechanical flip-up sight was previously mounted on the RIS rail.
On the barrel, we find two-sided manipulators - a magazine release and a fire selector.
Importantly , the model features licensed Sig Sauer markings - at the magazine seat, barrel, pistol grip and on the magazine itself - a tribute to the fans of the original markings found on firearms.
The MPX-K Sportline is equipped with a folding buttstock, which will reduce the length of the replica during transport or shorten it to a minimum during CQB matches. On the butt we will find QD mounts
Inside we will find a modified V2 gearbox, a quick-change spring system, steel gears and a rotating hop-up chamber.
The replica comes with wiring to the front.

Battery included![]() NiCd
rechargeable battery is characterized by high efficiency
current-carrying capacity, but there are disruptive effect on memory.
Should be unloaded and loaded in the full cycle, ie, it is recommended
to fully discharge, and after unloading must charge the battery
immediately without leaving it for a long time in a discharged state. | No |

Muzzle velocity [FPS]![]() It is the spped of bb, while its leaving the innerbarrel of replica. This speed is measured in FPS (Feet Per Second). 1 FPS = 0,3 m/s 1 J = 99 m/s 1 J = 326,7 FPS | 230 |
| Fire mode | Full-auto Semi-auto |
Gearbox version![]() Indications v2, v3, v6 does not mean the level of advance, but only shape of gearbox skeleton which was used and selected by the manufacturer depending on the capabilities of the body of the replica. For example, a models of the M4/M16 family, MP5, have a v2 gearbox, while the AK family have gearbox v3. | Gearbox v2 modified |
Hop-Up![]() Hop-Up system is used for overclocking bb during the shot (putting it in rotation), through which, it extends its flight path. Acting laws of physics make that bb lift up, while the gravitational force take it down. Appropriate adjustment of Hop-Up, will compensate for these two factors, which result in long and straight flight for longer distance and be greater focus shot (to improve accuracy). | Yes |
