The B5 Systems M-LOK Rail Cover set provides a simple way to improve the handling surface of an M-LOK-equipped handguard while covering unused mounting slots. This exact Coyote Brown configuration includes four low-profile panels designed for use with most machined rails and polymer handguards that employ the M-LOK mounting system. Each cover uses a press-in fit and spans three M-LOK slots, allowing the panels to be positioned where additional traction and separation from a warm handguard are most useful. The soft rubber construction has a ribbed exterior that creates a secure, non-slip contact surface without the bulk of a conventional accessory rail or large hand stop. Its material is resistant to heat and chemicals, making the covers suitable for rifles that see regular range use, training, field handling, and routine maintenance. Each individual panel measures 4.6 inches long, 0.63 inch wide, and 0.28 inch high, maintaining a streamlined profile that follows the handguard closely. The four-piece package gives the user flexibility to cover multiple surfaces, arrange panels around other M-LOK accessories, or concentrate coverage along the normal support-hand position. The Coyote Brown color coordinates with similarly colored stocks, grips, vertical grips, and other rifle furniture while providing a distinct alternative to black or Flat Dark Earth components. Because these covers occupy M-LOK slots directly rather than adding an external rail section, they preserve a clean configuration and provide a comfortable gripping surface wherever bare slots would otherwise remain exposed. Manufactured in the United States, this B5 Systems set is a practical addition for configuring an M-LOK handguard for improved grip, comfort, and heat resistance without adding unnecessary complexity.Specifications and Features: Low-profile covers for M-LOK handguards Coyote Brown color Four rail covers per pack Each cover spans 3 M-LOK slots Press-in installation Soft, ribbed non-slip rubber construction Heat- and chemical-resistant material Each cover measures 4.6 x 0.63 x 0.28 inches Made in the USA Brand: B5 Systems Model: M-LOK Rail Cover Product Type: Rail Cover Set Manufacturer Part Number: RCM-1258 UPC: 814927022164
