VISM M-LOK Single Slot Rubber Rail Covers - 18 Pack

The VISM M-LOK® Single Slot Rubber Rail Covers by NcSTAR are designed to improve comfort, grip, and heat insulation on M-LOK handguards without adding unnecessary bulk. These low-profile covers install directly into individual M-LOK slots, smoothing sharp edges and protecting your support hand from heat generated during sustained firing.

Constructed from heat-resistant textured rubber, each cover provides a secure, non-slip surface while maintaining a slim footprint that won’t interfere with accessory placement. The hinged snap-in design allows for fast, tool-less installation. Simply lift the rear section, slide the front shoe into the M-LOK slot, and press down to lock the cover in place.

Ideal for AR-style rifles, PCCs, and modern sporting builds, these covers enhance handling and thermal protection while preserving the clean, modular nature of your M-LOK rail system. Each pack includes 18 individual slot covers, giving you flexible coverage options across your handguard.
