MCF (MLOK Cover, Forward Controls) is a collaboration between Railscales and Forward Controls Design.  Machined in G10, with the AA surface (All Angles, or dimpled) pattern we developed for our bolt catch (ABC/R), forward assist (LDFA), ambidextrous magazine release (EMR-A).  The AA concept was not developed for aesthetics, but as a versatile surface that offers equal traction from all angles of approach (thus the AA designation).  The AA surface can hardly find a better application than hand guard rail covers, where a user’s hand can have multiple angles of approach, and hold the hand guard in different ways.
The AA pattern on the MCF is made of two dimple sizes and depths,  a series of large perforations / drain holes are drilled along its length in the middle row of dimples.
MCF is available in two lengths: MCF-S (short, 3.2″, covers 2 MLOK slots) and MCF-L (long, 4.7″, covers 3 MLOK slots), both come standard with MLOK mounting hardware.
