The Magpul M-LOK rail covers are designed to protect the edges of your M-LOK mounting slots when they are not in use. The M-LOK system was designed by Magpul Industries as an upgraded option to an existing mounting system. The M-LOK concept has since become a free-license platform and allows for greater compatibility between various firearm manufacturers.

The M-LOK system is similar to the KeyMod system in that it permits the addition of more rail sections if needed. Unlike the KeyMod system, however, M-LOK uses straight slots instead of the keyhole shapes used in KeyMod. The M-LOK system is known to be gentler on polymer accessories than KeyMod. While the use of a conical nut in the KeyMod system can lead to weakening and deformation of the accessory, the cammed shank used in the M-LOK system ensures a safe and easy installation and removal of your accessory.

Why Do I Need M-LOK Rail Covers?

The large number of unused spaces on an M-LOK handguard can make it difficult to achieve a firm grip on your firearm. In wet weather conditions, this weakness of the M-LOK handguard can really take its toll. This Magpul M-LOK rail covers were designed to help combat the poor grip presented by M-LOK handguards.

The Magpul Rail Covers

These rail covers by Magpul are made from a heat-resistant flexible material for an improved grip surface. These rail covers come as a set of two to cover six full M-LOK slots. They can be trimmed for customized shaping if needed. If you are looking for a way to improve the functionality of your M-LOK handguard, consider these Magpul M-LOK rail covers.
