  • Aluminium construction

If you are rocking the Sig Air MPX and you are worried your battery will poke out of the handguard, worry no longer, Laylax have an innovative solution! The Handguard Battery Block for MPX AEG is designed to mount to the outer barrel using a grub screw and close the front end of the handguard up to stop your battery from hanging out when the SMG is pointed down. The block is constructed from aluminium with a matt black anodised finish and is styled to look like the gas block of the bigger MCX, meaning it shouldn't detract too much from the realistic looks of the MPX. This is why we love Laylax, they always come up with a nifty solution for these little niggles!

  • Steel construction
  • Ball bearing equipped spring guide
  • For Sig Air MPX Submachine Gun AEG

If you are upgrading your MPX AEG, a ball bearing spring guide is a great way to reduce stress on the gearbox and spring, and prolong the life of your internals when operating in high-strain setups. The Laylax Ball Bearing Spring Guide is designed for the MPX and is a quick and easy replacement thanks to its quick change functionality.

The spring guide is constructed from steel, which alone will prolong its life considerably, but the ball bearings in its base allow the guide to spin freely and redirect any stress on the gearbox shell, and the spring itself.
