Hardware-Free M-LOK Rail Covers

If you’re running an aluminum free-float handguard, you probably already know that things get hot when you start emptying magazines.  These M-LOK rail covers from Hexmag are a great way to beat the heat coming off your barrel, with a heat-resistant polymer barrier between your skin and hot metal.  Each pack of these comes with four covers for your M-LOK handguard, and each one covers 4 M-LOK slots, about 6 inches long.  These covers use Hexmag’s Wedgelock system, which is a simple, hardware-free solution for attachment.  Simply press the cover in, and it will expand behind the handguard for a perfect fit.  Each cover can be cut down to size if you have other accessories on the handguard.  If you need a custom fit for a grip, bipod, laser, or handstop, you won’t need to purchase additional pieces – you can use what’s on hand to get a perfect fit.


  • 4 rail sections per kit
  • Each piece covers 4 M-LOK Slots
  • Can be cut down to fit around grips, handstops, or other accessories
  • Fiber-reinforced polymer construction
  • Available in Black or Flat Dark Earth
