5KU KP-9 Spitfire Tracer Unit; 14mm CCW

Code: BBP-334
  • Tracer unit with muzzle flash
  • Fits 14mm CCW male threaded barrels
  • KP-9 Replica - Perfect for PP-19-01 AEGs and other SMGs

If you are looking for a Tracer Unit with Russian styling the KP-9 Spitfire Tracer Unit from 5KU is one to keep an eye on. This device is based on the real world MPI KP-9 flash suppressor used by Russian Special Forces with their PP-19-01 SMGs and is ideal for any 9mm style Airsoft SMG but will fit any Airsoft rifle with a 14mm CCW male threaded barrel.

This KP-9 isn't just about the looks either, inside you will find a Spitfire Tracer insert which illuminates green tracer BBs and provides a realistic muzzle flash effect each time you fire. The unit can be operated in flash only, tracer only or tracer and flash mode, giving plenty of options for the aggressive, the realism focussed and the more stealthy playstyles out there. Whether you run a PP-19 AEG or you are looking for the most menacing looking Spitfire tracer unit out there, this will do the trick!

Full description

BBs frequently purchased with this unit...


The real KP-9 flash suppressor is designed to eliminate muzzle flash, but this 5KU replica offers the exact opposite! The KP-9 Spitfire Tracer Unit mounts to 14mm CCW male threaded outer barrels and provides both muzzle flash and tracer unit functionality, with the option to turn off the muzzle flash when you want to sneak and turn off the tracer mode when you are using standard BBs while still enjoying realistic muzzle flash.

The device has a uniquely aggressive look, matching well with the general style of Russian inspired Airsoft replicas. Ideally used with a PP-19-01 AEG or GBB platform, the KP-9 is also compatible with any Airsoft gun with 14mm CCW male threads, though its real steel 9mm chambering makes it ideal for 9mm SMG replicas such as MP5/SMG-5, AR-9, Scorpion EVO and others.

The KP-9 Tracer Unit has an internal rechargeable lithium battery and can be recharged using a Micro-USB cable, one of which is included in the box. To access the charging port you will need to unscrew the rear cap of the unit, remove the internal spring and you will see the tracer insert which can be charged in place or removed from the body of the KP-9 to charge.

The activation button is also on the rear of the tracer insert and to turn the unit on you need to press it once (indicated with a single beep). Turning it off again requires a second press, and to confirm the unit is powered down it will emit two beeps. Mode selection is provided by the same button; simply press and hold the button for 2 seconds to scroll between muzzle flash & tracer, muzzle flash only and tracer only modes.

If you want a mean looking muzzle device with tracer functionality, they don't get much meaner than the 5KU KP-9. While it belongs on a Russian platform, the real world KP-9 appears on 9mm builds of all shapes, sizes and origins in the US civilian tactical community, so PP-19 or no PP-19, the KP-9 gives your primary a beastly look with tracer and muzzle flash functionality to back it up!
