BCM­ MCMR Rail Cover Kit


What’s Included | Specs | Pictures | Restrictions

The BCM MCMR rail covers are an ultra-slim solution that will work on almost any M-LOK surface. The radiused surface provides a round handguard feel from octagonal handguard profiles, typical on most modern rails. These rail covers can be cut to fit around accessories easily and can add some extra grip to an otherwise slick aluminum surface.
