Product Description

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 FCD’s 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.

Standard with MLOK mounting hardware included.
