At SENTRY®, 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. 

Features / Specifications:

  • Spans 4 M-Lok slots for convenient installation
  • Can be cut down for shorter lengths to fit around optics or hand stops
  • Made in the U.S.A.

    Awesome Rail Covers

    Posted by Tim Zdrazil on 20th Feb 2023

    Exactly as advertised. Fast shipping and great price. I used them to cover the M-Lok slots on my Kel-tec KS7. Highly recommend. They pop right in and have a great look and feel.

    Rail covers

    I have these on several rifles. They are a great product. The pattern gives them good grip and they’re wide enough to cover the rails well. Very secure - kind of a pain to put on sometimes secure as the fit is great. Definitely recommend

    I just got this in the mail and installed to my AR. Quality seems really good. I like the fit and feel - it fits snug and provides good grip.

    Rail Covers

    Wanted something instead of metal front grip. These are nice grips, easily installed, easy cut and fit. Nice appearance. Not perfect but not too far away. Waiting to see how they hold up to heat.

    M-lock Hand Rails

    Great Fit, Can be cut to size. Rubbery like material, will not break or crumble like other hand rails made of plastic composite.

    Great Product!

    Posted by Randall Stuhler on 25th Apr 2020

    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

    Posted by Jeff on 16th Mar 2018

    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!
