Laylax Outer Barrel Base & Battery Block Set for SigAir MPX

  • Aluminium construction 
  • 14mm CCW male threaded tip
  • For SigAir MPX AEG

If you want your SigAir MPX even shorter than it comes from the factory this kit will do it! The Laylax Outer Barrel Base & Battery Block Set for SigAir MPX includes a super short outer barrel base and the Laylax Battery Block, allowing you to install a barrel extension or a suppressor which runs beneath the handguard for the integrally suppressed look. 

This part replaces your original outer barrel with an aluminium barrel base measuring 8.5cm overall length, with 4.5cm protruding ahead of the receiver when installed. Also included is the Laylax battery block, designed to keep your battery contained within the handguard when your barrel is pointed down. The battery block won't fit over a suppressor but if you decide to fit a barrel extension it should fit any with a diameter of less than 19mm.
