We Live to Protect, so don’t leave your firearm rail unprotected. A nicked or dinged gun rail can create an inconsistent mounting surface for your optics, and the rails themselves can be sharp. So protect yourself and your gear with SENTRY's low-profile rail covers, available for M-Lok®, KeyMod, and Picatinny rail systems in a high-performance, non-slip design. They look amazing, function better than others on the market and complete your rifle’s ability to get the job done. SENTRY M-Lok® rail covers use the patented Wedgelok® technology to hold it securely to your hand-guard. When installing simply press each section firmly into each M-Lok® slot. Once the Wedgelok® is in place it will expand and lock in behind the hand-guard. 

  • Spans 4 M-Lok slots for convenient installation and can be cut down for shorter lengths to fit around optics or hand stops.
  • Available in Black or FDE

    Great Product!

    I was researching products that were made of flexible material, durable, and looked good. These rail covers are all of that and more. I use a Magpul AFG2 front grip. Using these rail covers (2 per side) on each side of the AFG2 add support, grip, and a great feel. I highly recommend these to anyone looking for low profile rail grips.

    Works perfectly

    Got two sets of these for a couple of new rifles that I just received and these covers fit perfect and gave a more comfortable secure grip on the hand guards. Only issue is they were backordered for a while, but are worth the wait!
