The barrel is finished in bronze and has authentic looking mock locking lugs across its upper surface, with "9x19" marked on the chamber area in recessed lettering. The barrel has a standard flared profile which tapers towards the chamber, matching the more common real steel Hi-capa barrels perfectly.

  • Aluminium construction
  • 14mm CCW Male threading
  • For Sig Air MCX Virtus AEG

If you want to shorten your MCX down a bit or you are going for a slick integrally suppressed look for your next build this outer barrel from Laylax is just what you need. This barrel is 6.5 inches (17cm) in overall length and is constructed from aluminium for a perfect balance between low weight and strength.

At the tip of the barrel, we are treated to 14mm CCW male threading, allowing you to equip your MCX with a suppressor for sneaky duties. The tip of the barrel is wide enough to allow an inner barrel to pass straight through, meaning no need to mod it if you want to keep the original MCX inner barrel length. If installed on a standard MCX the barrel will be entirely beneath the handguard, allowing you to mount a tracer unit or suppressor without increasing the overall length of your setup and give your rifle the "Honey Badger" look. If you are adding a tracer make sure you get a shorter inner barrel as well!
