5KU 7" Aluminium Outer Barrel for M4/AR-15 AEGs

If you are working on your CQB build you must be looking for the shortest barrel out there, and right now, this is it! The 5KU 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 to be shorter this will get you halfway there, but don't forget you'll need a shorter inner barrel too!
