  • 14.5" Heavy profile barrel - 14mm CCW male threads
  • Compatible with M4/AR15 AEG rifles

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.

This is why we love Laylax, they always come up with a nifty solution for these little niggles!
