5KU Airsoft

If you are working on your CQB build you must be looking for an extremely short outer barrel, and this one certainly is that! The 5KU 8.7" Aluminium Outer Barrel For M4/AR-15 AEG is compatible with most M4/AR-15 AEGs and is constructed from aluminium for a perfect balance between low weight and high strength. 

The barrel is threaded at the tip with common 14mm CCW male threading, meaning you can mount the most common muzzle devices on the market with ease, including tracer units, suppressors and flash hiders in various styles. Also present are grooves in the underside to allow a gas block or M4/AR-15 triangular front iron sights to be mounted, though this is not essential. If you need your M4 Airsoft rifle to be shorter this will get you halfway there, but don't forget you'll need a shorter inner barrel to match!

If you are building an M4 from the ground up or you want a new look for your M4/AR15 platform this 5KU Aluminium outer barrel is worth a look! This barrel is 14.5 inches in length, just like the standard carbine length M4 barrel but has a heavier profile towards the tip to simulate real-world heavy barrels which allow for more sustained fire before accuracy takes a dive due to heat build-up.

The barrel is constructed from two parts, the barrel itself and the barrel base which are secured together using a pair of steel grub screws. At the tip we have the Airsoft standard 14mm CCW male threading, leaving you with a wealth of options for what muzzle device you choose to mount. The profile of the barrel matches real M4 barrels throughout its length, making this a great choice as a replacement for those who don't like seeing what is clearly a skinny Airsoft barrel through the ports on their handguard. This barrel is designed for M4/AR15 AEGs and should fit the vast majority of them.

If you're after an ultra-compact tracer unit which works on pistols and rifles, the 5KU Compact SPITFIRE Tracer Unit is the way to go! Packaged with rear collars for both 14mm CCW male and 11mm CW female barrel threads, this uniquely lightweight and slim tracer unit is ideal for GBB pistols but also works a treat on any 14mm CCW threaded AEG or GBBR.

The unit is powered by an internal rechargeable battery, which can be recharged via the included USB Type-C cable, making it economical to run and keeping the form factor as small as possible. The activation switch and charging port are on the rear of the unit, accessible with the rear collar removed. One of its most impressive features is the ability to "Quick Charge", allowing you to charge the unit for 5 minutes and get approximately 1000 tracer shots before power runs out. Another outstanding feature is the "Auto Standby" and "Shake to Wake" modes, saving your battery power by turning the unit off after 5 minutes of inactivity and turning it on again as soon as movement is detected.

Whether you're running a compact rifle or a GBB pistol, the 5KU Compact SPITFIRE Tracer Unit is ideal for either role. Affordable and packed with advanced features, but remarkably light, slim and short, the Compact SPITFIRE is a fantastic unit for whatever you use it for!
